In this research, we suggest a novel Fully/Convolutional/Neural/Network/(F-C-N) engineering meaning to help the identification of variations from the norm, for example, polyps, ulcers, also blood, in gastrointestinal (G/I) endoscopy pictures. The projected engineering, termed Look-Behind/MFCN/(LB-MFCN), is fit for removing multi-scale picture includes through utilizing squares of similar convolutional coatings with various channel sizes. These squares are associated through Look-Behind (LB) associations, so the highlights they produce remain joined through highlights removed since behind layers, accordingly protecting the particular data. Besides, it has fewer open, limitations than regular Convolutional/Neural/Network-(C/N/N) structures, which creates it reasonable on behalf of preparing through littler datasets. This is especially valuable in restorative picture examination subsequently information accessibility is generally restricted payable to ethicolegal limitations. The presentation of LB-MFCN is assessed on together adaptable also remote case endoscopy datasets, arriving at 99.82% as well as 95.50%, as far as Area Beneath accepting working Characteristic individually.

Automated pavement distress recognition is a key step in smart infrastructure assessment. Advances in deep learning and computer vision have improved the automated recognition of pavement distresses in road surface images. This task remains challenging due to the high variation of defects in shapes and sizes, demanding a better incorporation of contextual information into deep networks. In this paper, we show that an attention-based multi-scale convolutional neural network (A+MCNN) improves the automated classification of common distress and non-distress objects in pavement images by (i) encoding contextual information through multi-scale input tiles and (ii) employing a mid-fusion approach with an attention module for heterogeneous image contexts from different input scales. A+MCNN is trained and tested with four distress classes (crack, crack seal, patch, pothole), five non-distress classes (joint, marker, manhole cover, curbing, shoulder), and two pavement classes (asphalt, concrete). A+MCNN is compared with four deep classifiers that are widely used in transportation applications and a generic CNN classifier (as the control model). The results show that A+MCNN consistently outperforms the baselines by 1∼26% on average in terms of the F-score. A comprehensive discussion is also presented regarding how these classifiers perform differently on different road objects, which has been rarely addressed in the existing literature.

In recent years, image classification on hyperspectral imagery utilizing deep learning algorithms has attained good results. Thus, spurred by that finding and to further improve the deep learning classification accuracy, we propose a multi-scale residual convolutional neural network model fused with an efficient channel attention network (MRA-NET) that is appropriate for hyperspectral image classification. The suggested technique comprises a multi-staged architecture, where initially the spectral information of the hyperspectral image is reduced into a two-dimensional tensor, utilizing a principal component analysis (PCA) scheme. Then, the constructed low-dimensional image is input to our proposed ECA-NET deep network, which exploits the advantages of its core components, i.e., multi-scale residual structure and attention mechanisms. We evaluate the performance of the proposed MRA-NET on three public available hyperspectral datasets and demonstrate that, overall, the classification accuracy of our method is 99.82 %, 99.81%, and 99.37, respectively, which is higher compared to the corresponding accuracy of current networks such as 3D convolutional neural network (CNN), three-dimensional residual convolution structure (RES-3D-CNN), and space–spectrum joint deep network (SSRN).
