When taking images underwater, we often find they have low contrast and color distortions since light passing through water suffers from absorption, scattering, and attenuation, making it difficult to ...

We propose a learning-based low-light image enhancement algorithm, called the histogram-based transformation function estimation network (HTFNet), that estimates transformation functions using the ...

What did you do? Trying to obtain the histogram of a image of mode "LA". What did you expect to happen? Get the correct histogram. What actually happened? Got the wrong histogram. It seems that the ...
