Abstract: The main aim of this project is that implemented image enhancement aspect of guided image filtering techniques. Principle objective of Image enhancement is to process an image so that result is more suitable than original image for specific application. Digital image enhancement techniques provide a multitude of choices for improving the visual quality of images. A survey on directional filter, which defines the splitting of the input image into eight parts and reconstruction in to a single image after image enhancement. It generates the filtering output by considering the content of a guidance image, which can be the input image itself or another different image. This project will provide an overview of underlying concepts, along with algorithms commonly used for image enhancement.
Keywords: 1D Gabor filter, 1D Gaussian filter, DMF, DFB, and STFT.
