Embodiment 1
[0063] A part-reference quality assessment method for super-resolution reconstructed images based on wavelet transform. The steps of the evaluation method described in this embodiment are:
[0064] The first step: for the size such as figure 1 The m × n low-resolution image shown in I o and sizes like figure 2 The p×q super-resolution reconstructed image I shown s Block separately.
[0065] The low resolution image I o The step size of the processing window is s 1 , low-resolution image I o The size of the processing window is m 1 ×n 1 , the super-resolution reconstructed image I s The step size of the processing window is s 2 , the super-resolution reconstructed image I s size is p 1 ×q 1 :
[0066]
[0067]
[0068] For low-resolution images I o and super-resolution reconstructed image I s After block, M image blocks are obtained respectively:
[0069]
[0070] In formula (1)~(3):
[0071] m×n represents the low-resolution image I o The size of m...
