| Abstract: | In order to meet the needs of highprecision and realtime target information extraction from microvision images in the micronano and biological fields,a kind of realtime segmentation method of microvision images with uneven illumination based on multiresolution threshold was proposed.Because the traditional methods are difficult to estimate the threshold accurately in microvision image with uneven illumination and consume too much time,firstly,the energy function of gray intensity distribution was establishe... |
