- W2087315219 abstract "In crease detection of feather's quill, aim at the phenomenon that noise is also enlarged during the course of enhancing crease edge, a method of crease detection for feather's quill based on coupling shock filter and complex diffusion is proposed. The method based on the fact that shock filter can sharpen and enhance image edge and the real part of complex diffusion can reduce the noise, meanwhile the imaginary part can detect edge. Then the idea of coupling shock filter and complex diffusion is adopted. In the coupling process, shock flow velocity is controlled by the second derivative of image and time dependency is incorporated to the process. This lead to the result that shock filter is controlled by the imaginary part of complex diffusion. By comparing the simulation results, it is seen that with this method the real part and the imaginary part of complex diffusion can both effectively reduce the noise, and the imaginary part can also better enhance image edge. The experimental results show that the method improved significantly the visual quality of feather's quill image and can effectively detect the crease defects." @default.
