cv_equalizehist_image

It is a method that improves the contrast in an image, in order to stretch out the intensity range.

Calling Sequence

img_ret=cv_equalizehist_image(Image)

Arguments

Image

Input Image

img_ret

Image returned after applying method of equalizing Histogram

Description

To Equalize the Histogram by equalizing the intensity at different places in Image.

Histogram equalization is good when histogram of the image is confined to a particular region. It wont work good in places where there is large intensity variations where histogram covers a large region, ie both bright and dark pixels are present fir more details see: http://opencv-python-tutroals.readthedocs.org/en/latest/py_tutorials/py_imgproc/py_histograms/py_histogram_equalization/py_histogram_equalization.html

Examples

image_ret = cv_equalizehist_image(input_image);
