WebThe system captures the video frames from two cameras periodically and synchronously, using the adaptive image binarization based on the linear average threshold for the pretreatment, then processing with edge detection and filtering in the cross-directions at the same time. ... J. Bernsen, “Dynamic Thresholding of Gray Level Image,” ICPR ... WebThe global thresholding method [24, 25, 36] converts a gray-level image into a binary image based on an image intensity value called global threshold, which is invariant in the whole image domain. For images with an obvious bimodal histogram, global binarization methods are effective.
