FakeHDR: Can't call setPixels() on a recycled bitmap #24

Closed lionelmessi closed 8 years ago

Hi Diego,

I am trying to use the FAKE HDR in Android but I get this error on using it. Can you help in providing pointers as to where to look.

Thanks!

I have a grayscale image and would like to enhance the quality in terms of brightness and contrast (Somewhere on the lines of Matlab: imadjust, adapthisteq). The original images appear to be washed out.

Which function would you like to suggest for this kind of problem? I also looked at AdaptiveContrastEnhancement() but not able to figure out good values for the contants! Any help is highly appreciated.

Hello lionelmessi,

The FakeHDR is fixed. This filter is expensive to work in Android because needs at least 2 copy of the image, and the Android has a memory limitation. To achieve the results of imadjust, you can use HistogramAdjust (works in RGB too :)). You can try others filters as: Clahe, HistogramEqualization, HistogramStretch.

Cheers !

Ohh great! BTW I wrote that myself yesterday but pulled and compared with you. Works awesome!
