Problems solved by technology

However, these methods cannot solve the situation that the width of the same object in the left and right views is different, and in the video, the segmentation process of the following frame depends on the segmentation result of the previous frame, so the error of image segmentation is transitive, and the subsequent stereo matching is also based on The results of image segmentation, so the accuracy of the existing methods can not meet the requirements

Abstract

The invention discloses a division method of a holographic video stream and relates to the technical field of holographic images. The division method comprises the following steps: assuming that one video stream has n frames, namely F1, F2 ...Fn; carrying out image division on a certain frame Fi to obtain divided areas Si1, Si2,...Sim; given that an image division process is Seg(x), solving a similarity function to be Sim(x, y) and a similarity threshold value to be V; and converting an adjacent-frame correlation into {Tk(x)}, k=1, 2 ...27. According to the division method of the holographic video stream, disclosed by the invention, the image division is carried out on the basis of pixel colors, and traditional image division does not need to be carried out on each frame under the condition that widths of the same objects in left and right views are different; and on the basis of keeping the division accuracy of an original algorithm, an image division speed is extremely improved.

Description

technical field [0001] The invention relates to the technical field of holographic images, in particular to a method for dividing a holographic video stream. Background technique [0002] Image segmentation technology originally originated from the field of pure image processing research, but in recent years, it has taken more and more weight in the research direction of holographic stereo vision. In short, image segmentation is to divide an image into two or more sub-images according to certain rules, which is the basis and premise of subsequent image analysis. The rules of division are mainly based on the adjacency, correlation and common characteristics of pixels. Usually these pixels come from the same object, and then the image area of ​​this object can be processed directly, instead of pixel independent. processing, improving the efficiency of image processing. [0003] As far as the current image segmentation algorithms are concerned, it can be described as diverse,...
