[0032] The technical solutions of the present invention will be described in detail below with reference to the specific drawings and embodiments, which are not intended to limit the protection scope of the present application.
[0033] The present invention is a color image reconstruction method based on local data block tensor enhancement technology (referred to as method, see Figure 1-4 ), the method comprises the following steps:
[0034] Step 1: The image to be reconstructed is a single size of 2 p ×2 p Take the standard color image of ×3 as an example, denoted as is the field of real numbers, and p is a positive integer; The image after randomly missing part of the data is For the random missing operator Ω acts on obtained from above, The gray value at the missing data is 0, and the known data is in The position in is the index position;
[0035] The local data block is used as the tensor enhancement unit for structured addressing, the pixels of the imag...
