Machine vision technologies are increasingly ubiquitous in society and have become part of everyday life. However, the rapid adoption has led to ethical concerns relating to privacy, bias and accuracy. This paper presents the methodology and some preliminary results from a digital humanities project that is mapping and categorising references to and uses of machine vision in digital art, narratives and games in order to find patterns that may help us understand the broader cultural understandings of machine vision in society. Understanding the cultural significance and valence of machine vision is crucial for developers of machine vision technologies, so that new technologies are designed to meet general needs and ethical concerns, and ultimately contribute to a better, more just society.

The issue that underlies a worrying question of maternal and child health in Côte d'Ivoire is that of social logic. Social logic is perceived as "cultural constructions of actors with regard to morbidity that cause to adopt reproductive health care". Based on this understanding, the concept of social logic in reproductive health is similar to a paradigm that highlights the various factors that structure and organise sociological resistance to mothers' openness to healthy reproductive behaviours; that is, openness to change for sustainable reproductive health. Far from becoming and remaining a prisoner of blind culturalism with the social logic that generates the health of mothers, new-borns and children, practically-relevant questions are raised. Issues of "bad governance", socio-cultural representations and behaviours in conflict with modern epidemiological standards are addressed in a culturally-sensitive manner, an important issue for the provision of care focused on the needs of mothers seeking answers to health problems. Developing these original community characteristics helps to orient a reading list in a socioanthropological perspective with a view to explaining and understanding different problems encountered, experiences acquired by social actors during the implementation of antenatal, postnatal and family planning care. This context of building logic with regard to reproductive health care is key to identifying real bottlenecks in maternity services and achieving efficient management of maternal, new-born and child health care for the benefit of populations and actors in the public health sector.

In order to further improve the energy efficiency of classroom lighting, a classroom lighting energy saving control system based on machine vision technology is proposed. Firstly, according to the characteristics of machine vision design technology, a quantum image storage model algorithm is proposed, and the Back Propagation neural network algorithm is used to analyze the technology, and a multi­feedback model for energy­saving control of classroom lighting is constructed. Finally, the algorithm and lighting model are simulated. The test results show that the design of this paper can achieve the optimization of the classroom lighting control system, different number of signals can comprehensively control the light and dark degree of the classroom lights, reduce the waste of resources of classroom lighting, and achieve the purpose of energy saving and emission reduction. Technology is worth further popularizing in practice.

Abstract For research in the field of illumination estimation and color constancy, there is a need for ground-truth measurement of the illumination color at many locations within multi-illuminant scenes. A practical approach to obtaining such ground-truth illumination data is presented here. The proposed method involves using a drone to carry a gray ball of known percent surface spectral reflectance throughout a scene while photographing it frequently during the flight using a calibrated camera. The captured images are then post-processed. In the post-processing step, machine vision techniques are used to detect the gray ball within each frame. The camera RGB of light reflected from the gray ball provides a measure of the illumination color at that location. In total, the dataset contains 30 scenes with 100 illumination measurements on average per scene. The dataset is available for download free of charge.

Video traffic data were collected in 24 combinations of four different camera position parameters. A machine vision processor was used to detect vehicle speeds and volumes from the videotapes. The machine vision results were then compared with the actual vehicle volumes and speeds to give the percentage errors in each case. The results of the study provide a procedure with which to establish camera position parameters with specific reference points to help machine vision users select suitable camera positions and develop appropriate measurement error expectations. The camera position parameters that were most likely to produce the least overall volume and speed errors, for the specific site and field setup with the parameter ranges used in this study, were the low height of approximately 7.6 m (25 ft), with an upstream orientation (traffic moving toward the camera), a 50-mm (midangle) focal length, and a 15° vertical angle.
