It's interesting to read a technical document today about detecting dirty areas in low contrast images (dirty here refers to the parts darker than other areas, which may not be visible to human eyes).
1. Low contrast image dirty area detection
Start with the above figure: If the first picture is not marked, I can't find the ...

1, Introduction to sparse representation
Sparse representation theory Sparse representation uses a linear combination of fewer basic signals to express most or all of the original signals. After sparse representation, the more sparse the signal, the higher the accuracy of the reconstructed signal. Let x ∈ Rn be the signal to be processed, ...
