Abstract
The method for forming a three-dimensional threshold three-dimensional figure based on a double grayscale factor belongs to the technical field of image processing; the method performs the following steps in sequence: counting the number of pixels in a certain pixel grayscale level; counting the number of pixels in two neighborhood grayscale levels ; Count the number of pixels in the gray level of a certain pixel, the gray level in the first neighborhood, and the gray level in the second neighborhood, build a regular cube, and fill the number of pixels into the grid; The ellipsoid is established based on the gray level tolerance of a neighborhood; the ellipsoid is placed according to the rules; the ellipsoid is moved; the area where the ellipsoid traversal space intersects with the regular cube is reserved to obtain a three-dimensional threshold stereographic; the present invention is based on The three-dimensional threshold three-dimensional graphics formation method with dual grayscale factors can display multi-dimensional thresholds and corresponding pixel numbers in a three-dimensional image, which is conducive to dynamically observing the influence of threshold changes on the image segmentation effect and finding the best segmentation threshold.
Description
technical field [0001] The invention relates to a method for forming a three-dimensional threshold three-dimensional figure based on double gray scale factors, which belongs to the technical field of image processing. Background technique [0002] Threshold segmentation method is a region-based image segmentation technology, the principle is to divide the image pixels into several categories. Image thresholding segmentation is a traditional and most commonly used image segmentation method. Because of its simple implementation, small amount of calculation, and relatively stable performance, it has become the most basic and widely used segmentation technology in image segmentation. It is especially useful for images where the object and the background occupy different gray scale ranges. It can not only greatly compress the amount of data, but also greatly simplify the analysis and processing steps, so in many cases, it is a necessary image preprocessing process before image a...
