Feature Enhancement in Visually Impaired Images
Abstract– One of the major open problems in computer vision is feature detection in visually impaired images. In addition, describe a potential solution using Phase Stretch Transform, a new computational approach for image analysis, edge detection and resolution enhancement that is inspired by the physics of the photonic time stretch technique.Here mathematically derive the intrinsic nonlinear transfer function and demonstrate how it leads to superior performance at low contrast levels and a reconfigurable operator for hyper dimensional classification and prove that the Phase Stretch Transform equalizes the input image brightness across a range of intensities resulting in high dynamic range in visually impaired images.Also show further improvement in the dynamic range by combining our method with the conventional techniques. Finally, our results propose a new paradigm for the computation of mathematical derivatives via group delay dispersion operations.
