[0134] Example 1
[0135] The example of figure (8) adopts the vector representation method shown in figure (2). In the case of retaining the same amount of data, Figure (8) shows the average value of the peak signal-to-noise ratio (PSNR) of all image frames of the reconstructed video with two residual data processing methods (the method in the present invention and the DCT method) Comparison. The specific steps implemented in this example will be described in detail below in conjunction with the method of the present invention, as follows:
[0136] (1) Use the vector representation method shown in Figure (2) to represent each frame of residual image as:
[0137] Frame = y _ vectors ∈ R D × N ...

[0148] The example of figure (9) adopts the vector representation method shown in figure (3). In the case of retaining the same amount of data, Figure (9) shows the average value of the peak signal-to-noise ratio (PSNR) of all image frames of the reconstructed video by two residual data processing methods (the method in the present invention and the DCT method) Comparison. The specific steps implemented in this example will be described in detail below in conjunction with the method of the present invention, as follows:
[0149] (1) Use the vector representation method shown in Figure (3) to represent a set of continuous residual images as:
[0150] GOP = y _ vectors ∈ R D × N ...
