Abstract The main aim of this paper is to propose a new technique for enhancing the
contrast of dark images using Dynamic Stochastic Resonance (DSR) and Multi
Wavelet Transform (MWT), which is computationally more efficient than the
conventional methods. In the work, for enhancing the contrast of dark images,
the intrinsic noise (darkness) of dark images has been used. The proposed
MWT-based DSR scheme (MWT-DSR) can yield better performances in terms of
visual information and color preservation than already reported techniques. The
desired output response is validated by the Relative Contrast Enhancement
Factor (F), Perceptual Quality Measures (PQM) and Color Enhancement… More >
