Green plums have produced significant economic benefits because of their nutritional and medicinal value. However, green are affected by factors such as plant diseases insect pests during growth, picking, transportation, storage, which seriously affect the quality products, reducing At present, in detection plum defects, some researchers applied deep learning to identify surface defects. recogn...

PURPOSE The purpose of this study is to assess color vision abnormalities in a cohort of subjects with type II diabetes and elucidate associated risk factors. METHODS Subjects were recruited from follow-up cohort of Sankara Nethralaya Diabetic Retinopathy Epidemiology and Molecular Genetics Study I. Six hundred and seventy-three eyes of 343 subjects were included from this population-based st...

Purpose – The purpose of this paper is to develop a robot vision system for surface defect detection of 3D objects. It aims at the ill-defined qualitative items such as stains and scratches. Design/methodology/approach – A robot vision system for surface defect detection may counter: high surface reflection at some viewing angles; and no reference markers in any sensed images for matching. A fi...

For several real-world problems, the mathematical methods of signal and image processing are most successful when they also incorporate the insight offered by the physics of the problem. Imaging systems are a particularly fertile ground for problems in this class because they deal specifically with the capture of physical scenes and with the reproduction of images on physical devices. Solutions...

We used Southern blot hybridization to study X chromosome-linked color vision genes encoding the apoproteins of red and green visual pigments in 134 unselected Caucasian men. One hundred and thirteen individuals (84.3%) had a normal arrangement of their color vision pigment genes. All had one red pigment gene; the number of green pigment genes ranged from one to five with a mode of two. The fre...

Vision System Alternatives Just as with electronic test equipment, there are several classes of vision inspection equipment. • The machine-vision industry has a wide range of equipment vendors and systems integrators for ‘rack and stack’ vision systems. Software tool-kits provide an extensive suite of image-processing algorithms and graphical tools to simplify the programming of inspection task...

Steel is the material of choice for a large number and very diverse industrial applications. Surface qualities along with other properties are the most important quality parameters, particularly for flat-rolled steel products. Traditional manual surface inspection procedures are awfully inadequate to ensure guaranteed quality-free surface. To ensure stringent requirements of customers, automate...

The majority of machine vision systems derive their input data by digitising an image to produce a square grid of sampled points. However, other sampling techniques can represent equal picture information in a smaller number of samples, with a consequent reduction in data rate. Several workers have looked at regular hexagonal sampling of images which produces optimum data rates for a given info...
