Image Enhancement Using Guided Image Filter and Wavelet Based Edge Detection
Journal Title: International Journal of Modern Engineering Research (IJMER) - Year 2013, Vol 3, Issue 3
Abstract
- This paper proposes a new method for image enhancement by incorporating the concept of guided image filter and wavelet based edge detection. Guided image filter is a spatial domain filter performs the filtering by considering the content of the guidance image, which can be the input image itself or another different image. Guided image filter has no gradient distortion and better performance near the edges. Wavelet based edge detection which is a frequency domain approach is used here for edge detection. It has better performance than any other edge detection methods such as Roberts, sobel operators. This method helps tosuppress the noise while preserving the edges. The experimental results prove that the proposed imageenhancement method outperforms other methods in both subjective and objective quality, peak-signal-to-noiseratio(PSNR).
