As the population increases, urbanization will gradually reduce the area of cultivated land, and the pressure on the agricultural system will continue to increase. In traditional agriculture, there is a reliance on mechanical operations, with manual harvesting as the basis, resulting in high costs and low efficiency. Quality control of agricultural products helps to judge and determine the quality of products and promotes their commercialization. With the development of computer vision technologies, automatic sorting and quality control of agricultural products has been achieved, and computer vision systems have been widely used in various areas of agricultural and food production market segments, avoiding the high cost and low efficiency of traditional operations.

Abstract This paper presents a computer vision system for evaluating the quality of deburring and edge breaking on aluminum and steel blocks. This technique produces both quantitative (size) and qualitative (quality) measures of chamfering operation from images taken with an off-the-shelf camera. We demonstrate that the proposed computer vision system can detect edge chamfering geometry within a 1–2mm range. The proposed technique does not require precise calibration of the camera to the part nor specialized hardware beyond a macro lens. Off-the-shelf components and a CAD model of the original part geometry are used for calibration. We also demonstrate the effectiveness of the proposed technique on edge breaking quality control.

Abstract After a brief introduction to the generic aspects of automation in analytical laboratories, the different approaches to quality in analytical chemistry are presented and discussed to establish the following different facets emerging from the combination of quality and automation: automated analytical control of quality of products and systems; quality control of automated chemical analysis; and improvement of capital (accuracy and representativeness), basic (sensitivity, precision, and selectivity), and complementary (rapidity, cost, and personnel factors) analytical features. Several examples are presented to demonstrate the importance of this marriage of convenience in present and future analytical chemistry.

Throughout their existence, civilized peoples have been turning their environment into desert. The causes of desertification are well known—overgrazing, the felling of trees for fuel, and bad agricultural practices. Their effects are apparent in disasters such as the Sahel drought and recent famines in Ethiopia, the Sudan, and elsewhere. The population explosion enhances the extent of the environmental degradation. More agricultural land is currently being lost through salinization and waterlogging than is being created by new irrigation schemes, but this is only part of a problem that faces all tropical third-world countries and for which multinational organizations and the affluent nations of temperate regions are, regrettably and often unknowingly, largely responsible.Because the poorer countries receive, for their agricultural products, cash of which the market value does not take into account the cost to the environment of overexploiting the land, they are apparently doomed to a vicious circle of increasing poverty, deprivation, and famine. Yet it is not beyond the abilities of civilization to devise a viable scheme, based upon sound ecological principles, by which the quality of life of desert peoples could be immeasurably improved. Instead of trying to change the land to make it conform to present economic and political expectations, development should be adapted to exploit the potentialities of the environment as it exists. Such a scheme, profiting from the diversity of microenvironments that occur in desert regions, would encompass multiple land-use and the development of numerous small agricultural and other projects—rather than the large-scale schemes hitherto initiated in fragile environments, and which have so often led to large-scale disaster. By adopting it, the world would simultaneously be made both more stable and more productive for the benefit of all its inhabitants.

Human validation of computer vision systems increase their operatingcosts and limits their scale. Automated failure detection canmitigate these constraints and is thus of great importance to thecomputer vision industry. Here, we apply a deep neural networkto detect computer vision failures on vehicle detection tasks. Theproposed model is a convolution neural network that estimates theoutput quality of a vehicle detector. We train the network to learnto estimate a pixel-level F1 score between the vehicle detector andhuman annotated data. The model generalizes well to testing data,providing a mechanism for identifying detection failures.

Long dan Xie gan pill is a traditional complex compound preparation with a long history for treatment of diseases, including hepatocolic hygropyrexia, dizziness, tinnitus, and deafness. Quality of products from different manufacturers may be varied. Since the current standard could not control the quality of products in a comprehensive and effective way, this study aimed at establishing a practical and convenient approach for holistic quality control of the preparation. This study included both qualitative and quantitative works to get information on the overall composition and main components, respectively. As a result, HPLC fingerprint (UV 240 nm) similarities of all fifty samples were in the range of 0.65∼0.99. Results indicated that there was a difference among products from different manufacturers. Additionally, ten characteristic peaks of the fingerprint were tentatively identified by LC-MS. Further chemometrics analysis was utilized to evaluate the products from different manufacturers. At the same time, the HPLC (UV 285 nm) multicomponent quantification result showed that contents of gentiopicrin, baicalin, baicalein, and wogonin were in the range of 0.61–5.40, 1.96–5.33, 0.10–3.40, and 0.046–1.16 mg·g−1, respectively. Data analysis verified the main different component of baicalein from the fingerprint statistical analysis. It is worth mentioning that the qualitative fingerprint and quantitative multicomponent determination were simultaneously accomplished by HPLC-DAD with dual channels. The study provided sound basis for improving quality control standards. This study also provided practical strategy for overall quality control of traditional Chinese medicines.

The increase in the production of agricultural products and food supplies in excess of regulatory needs and the provision of food safety in Russia led to the expansion of the export of agricultural products and the change in the course of the development of the agro-industrial complex from import substitution to export-oriented production. However, the entry to world food markets requires high quality of products from manufacturers and its certification in accordance with world standards. The article presents the organizational and economic transformations towards the greening of agro-industrial production, namely, the use of the resource potential, the involvement of Russian manufacturers in the production of environmentally friendly products and the development of organic agriculture; the mechanisms for solving the set problems are substantiated.

Quality being the competitiveness of the most important for the company's products and also because the quality has been the hope and desire of everyone, especially the consumer. Customers are not going to focus on a product / service only in terms of price but in good quality inherent in the product or service. Viewed from the importance of the quality of products, each company needs to spend quality, cost of quality is the cost refers to the cost incurred to prevent or expenses incurred as a result of producing a quality product. Efforts to improve the quality of the product will not run without the cost of quality control to overcome the problems faced by the company, where quality control can help the company determine the feasibility of the quality of products based on control limits have been set. This study aims to see how the cost of quality control and to analyze the efficiency of the implementation cost of quality control conducted by Aksan Bakery in Manado. Analysis of the data used is descriptive analysis with qualitative approach and using methods of presentation quality cost ratio analysis to assess the efficiency cost of quality. Based on analysis of the cost of quality control conducted by the company it appears that the cost of quality control conducted by the company do not meet the quality standards that have been set at 2.5% of sales, for the cost of quality issued by the company is greater than a predetermined quality standards, namely amounting to 13.89% of sales. This may imply that the cost of quality control has not been carried out efficiently. Keywords : Efficiency , Cost of Quality

The paper considers the possibility of solving the problem of improving the quality of technical vision using the contour method, which is used to position objects in mobile computer vision systems. The hardware part of the object positioning system includes two video cameras, a Raspberry Pi 3 microcomputer, a depth contour map screen, and a motor control unit. The codes of programs based on the OpenCV library, the algorithm of the system and examples of the implementation of the contour method are given. The algorithm of the developed positioning technique includes the selection of the contours of objects on the frames of a stereopair, removal of all open contours, calculation of the moment (center of mass) of each closed contour, determination of the displacement along the x-axis of the moments of the corresponding contours, filling each closed contour with points with a brightness inversely proportional to the displacement of the moments. The presence of two video cameras, a Raspberry Pi 3 microcomputer, a contour depth map screen provides stereoscopic and panoramic "vision", that is, the ability to determine the presence of objects and their distance, as well as to get an overall picture in the "field of view" of the system. The engine control unit allows mobile devices to avoid obstacles. Based on the analysis of the research results, it was found that the proposed system provides an increase in the quality of positioning of objects and a decrease in the required computing resource, which gives a significant decrease in power consumption and ensures the autonomy of the system.

Over the past two years, decrease in potato yield has been observed in the Moscow region. One of the main reasons is unfavorable weather conditions. To obtain a guaranteed yield, as well as to improve the quality of products, it is necessary to carry out reclamation works, including additional irrigation. Creation of the optimal water - air balance of the plant throughout the entire growing season will increase productivity, and improve the quality of agricultural products. Drip irrigation is the most economical method of irrigation, but its widespread use is hindered by the high proportion of manual labor when installing the drip tape. A mechanized method of laying the drip tape by placing the working equipment on the Grimme GF-75/4 comb former is offered. The existing methods for determining the irrigation rate do not consider the parameters of the humidification circuit, which leads to excessive irrigation and additional losses of irrigation water. The paper offers a method for determining the irrigation rate considering the shape of the humidification circuit and its geometric parameters.
