Abstract:
1. A digital image processing method implemented in a computer for generating a dilation image from a corresponding original digital image having a plurality of pixels, the method comprising: inputting the original digital image; generating an extended binary image by adding pixels to a boundary of the original image based on a structuring element and binarizing, utilizing a threshold value, each of the plurality of pixels of the original digital image and the pixels added to the boundary, wherein in the binarization process, each pixel is binarized in parallel; obtaining a processing image (b) from the extended binary image, wherein each pixel in the extended binary image having a value of 1 is identified as a pixel of interest in the processing image (b); obtaining a target image (T) from the extended binarized image, the target image being a same size as the original input image; generating a dilation image utilizing the processing image (b) and the target image (T), the dilation image being obtained by processing each target pixel in the target image in parallel by performing the following steps on the target pixel: after all target pixels in the target image have been processed according to the foregoing steps, thereby resulting in an updated target image, outputting the updated target image as an output image.
