A low-cost machine vision system with hardware capabilities of image processing is developed in this research. Several image process algorithms are designed for the developed vision system, namely, image quality selection, image recovery and resize, and image segmentation. All of these mathematical algorithms are programmed and implemented in a microchip using SOPC design tools. Furthermore, th...

In the domain of machine vision, the measurement of length is done using cameras where the accuracy is directly proportional to the resolution of the camera and inversely to the size of the object. Since most of the pixels are wasted imaging the entire body as opposed to just imaging the edges in a conventional system, a double aperture system is constructed to focus on the edges to measure at ...

The deburring processes of parts with complex geometries usually present many challenges to be automated. This paper outlines the machine vision techniques involved in the design and set up of an automated adaptive cognitive robotic system for laser deburring of metal casting complex 3D high quality parts. To carry out deburring process operations of the parts autonomously, 3D machine vision te...

This paper describes the tool life prediction model with end milling EN31 tool steel using P30 Tungsten uncoated carbide tool. The data set from the Taguchi method design is taken. For discussion the effects of cutting speed, feed rate and depth of cut on tool life of P30 are considered. This paper suggests a novel technique for the tool wear measurement based on machine vision. Tool images are...

grading science and grading equipment for many kinds of sea products are growing rapidly in developed communities and variety of grading equipment can be found in most of the large fishery units. computer vision has the potential to be used as a precise method for recognition and assessment of apparent characteristics. in this study, machine vision technology was used to sort fish based on spec...

Facial expressions are the most powerful and direct means of presenting human emotions and feelings and offer a window into a persons’ state of mind. In recent years, the study of facial expression and recognition has gained prominence; as industry and services are keen on expanding on the potential advantages of facial recognition technology. As machine vision and artificial intelligence advan...

The National Laboratory of Pattern Recognition (NLPR) at the Institute of Automation of the Chinese Academy of Sciences was established in 1987 to become one of the first national research laboratories in China. It has a large research team of staff and postgraduate students on computer and machine vision. and is a leading research laboraton in China in pattern recognition and computer vision. ...
