40. Sentencedict.com try its best to gather and build good sentences.

41. Histogram equalization is classical approach of image enhancement. But we usually equipoise the whole image one time, that will bring on insufficiency on the minutia part's enhancement.

42. By extracting encrustation of histogram, and calculating partial fuzzy extent around pixels to update the fuzzy roughness.

43. This procedure realize the function of image enhancement using histogram equalization method to achieve image enhancement.

44. To prevent the overflow and underflow problem, histogram modification is used.

45. Additionally, an image with a histogram that has pixels maxing out the left end will have a loss of detail in the dark areas.

46. The region histogram equalization is different from traditional histogram modification technology, the idea is based on human vision character and edge effect in image vision.
