This paper proposes a quality detection method of LED surface defects in dispensing back-end based on computer vision library HALCON. The key steps mainly include image preprocessing, image matching and defect detection, etc. Firstly, to choose the matching area automatically according to the regional characteristics of the LED chip. Secondly, image matching with standard template. Finally, complete...
In our recent studies, we identified 358 common cortical landmarks named Dense Individualized and Common Connectivity-based Cortical Landmarks (DICCCOL), each of which possesses consistent fiber connection patterns across individuals and populations and is thus predictive of brain function. However, the regularity and variability of the cortical folding shape patterns of these DICCCOLs are unknown...
Shape prior based segmentation method has the advantage of robustly tracking moving object. But, it can not deal with local rotations or changes of object structure. In this paper, we propose an algorithm that can accurately segment the moving foreground object with local rotation and object structure change from the low resolution gray scale images based on Schoenemann's method. Two new terms, turning...
A novel design of direct LED backlight is presented. The module is composed of white light LEDs, parabolic reflectors and novel lens caps. The predicted uniformity is up to 92%.
