Image Enhancement Using Python

Image Enhancement can be divided to Two class, the point processing and the histogram processing.

Point Processing

Six methods are used here, they are:

Po

  • Image Negative
    It's the simplest method to transform image using point processing
  • Thresholding Transformations
    set a threshold function
  • Logarithmic Transformations
    do the Log transformation to the image
    which can widen the image grey level
  • Powers-Law Transformations
    Also be called the famous Gamma transformation
  • Piecewise Linear Transformation Functions
    The enhanced edition of Thresholding Transformations

Histogram Processing

Use histogram to process image.
The most used method is called histogram equalization
