Image Histogram Equalization Stretch

Feature Description

Histogram equalization is a method to enhance image contrast. The main idea is to transform the histogram distribution of an image into an approximately uniform distribution. It is a non-linear stretch. The returned result type is a raster dataset (RasterRDD). For a description of image stretching, refer to Image Minimum Maximum.


Parameter description

Parameter Name Default Value parameter interpretation parameter type
RDD to Analyze   The RDD to be analyzed. RasterRDD
Minimum Target Pixel Value 0 The minimum target pixel value. Original pixel values are stretched between the minimum and maximum target pixels. The default is 0. Integer
Maximum Target Pixel Value 255 The maximum target pixel value. Original pixel values are stretched between the minimum and maximum target pixels. The default is 255. Integer
