Problems solved by technology
Specifically, the color of the target gray-scale frame can be restored by pixel point matching based on the gray-scale value, or the color of the source color frame can be copied to other gray-scale frames by calculating the motion vector, but there will be errors in the calculation of the motion vector and Not all pixels can be calculated as motion vectors. The effects of the above methods are flawed, or through a method of inter-frame block matching, the color of the corresponding block is replaced after matching the source color frame and the target grayscale frame. The entire sequence is colored, but the result of directly replacing the corresponding color of the block is often flawed, and block matching will also cause matching errors, coloring the video image is not accurate, resulting in color error propagation

The invention provides a video image processing method and processing device. The video image processing method comprises steps of choosing a to-be-colored video image to be processed from a to-be-colored video image set on the basis of a first deviation value between a to-be-colored video image of each frame in a to-be-colored video image set and a colored video image set and a second deviation value between the to-be-colored video image of each frame and other to-be-colored video images in the to-be-colored video image set, choosing a to-be-colored video image to be processed from the to-be-colored video image set, choosing a reference video image during a process of performing coloring on the to-be-colored video image from the colored video image set, performing coloring processing on the video image to be colored according to the reference video image, re-choosing a to-be-colored video image to be processed after coloring processing on the to-be-colored video image is completed to perform coloring processing until coloring processing is completed on all the to-be-colored video images in the to-be-colored video image set.
Description
technical field [0001] The present invention relates to the technical field of image processing, in particular to a video image processing method and a video image processing device. Background technique [0002] The goal of video image colorization is to color a sequence of consecutive grayscale video frames. There is a large similarity in the spatial domain between these video frames, which is of great help for coloring. [0003] In related technologies, based on the type of information transmitted between frames, there are mainly two methods for coloring video images: [0004] The first one: Draw the color line for auxiliary coloring in a certain frame as the reference information for color restoration of all frames. Specifically, when propagating the drawn lines, the color of the line can be propagated to the entire gray frame by solving the function equation, or the color can be propagated by using the geodesic distance as the weight, or the color can be propagated by...
