Modified Contrast Enhancement Algorithm Using Numerical Integration Simpson’s Method

This paper presents an efficient method to improve the contrast of low contrast images and at the same time provides satisfactory performances in terms of image contrast and sharpness. It is based on numerical cubic interpolation formula known as Simpson’s \(\frac{3}{8}\)th rule. The neighboring pixel information is used in interpolation method, and it gives the high contrast image and also preserves fine details of the images. Different quality-based parameters are used to measure the improvement of the contrast of the images. The obtained results are compared with various standard existing methods for further validation.
