16687a2655 Explicitly use double precision sin & cos in hough implementation
On some platforms sin and cos are calculated in single precision resulting in
diversity of results.

0bbba847a4 Fix equalization formula in equalizeHist function & rewrite in C++
Old implementation did

    lut[i] = 255 * (count(Y <= i)) / (width * height)

which actually shifts uniform histograms.
From now histogram is equalized as

    C = count(Y == min(Y))
    lut[i] = 255 * (count(Y <= i) - C) / (width * height - C)
