摘要： A single image deraining method is proposed. A wavelet transforming step processes an initial rain image to generate an i-th stage low-frequency rain image and a plurality of i-th stage high-frequency rain images. An image deraining step inputs the i-th stage low-frequency rain image to a low-frequency deraining model to output an i-th stage low-frequency derain image. A first inverse wavelet transforming step recombines the n-th stage low-frequency derain image with the n-th stage high-frequency derain images to form an n-th stage derain image. A weighted blending step blends a (n−1)-th stage low-frequency derain image with the n-th stage derain image to generate a (n−1)-th stage blended derain image. A second inverse wavelet transforming step recombines the (n−1)-th stage high-frequency derain images with the (n−1)-th stage blended derain image to form a (n−1)-th stage derain image, and sets n to n−1 and repeats the last two steps.

摘要： An image grid line removing method is used for removing grid lines of an image and includes a Fourier transform step, a Gaussian-like masking step and an inverse Fourier transform step. The Fourier transform step is for providing a Fourier transform to process the image to generate a frequency domain image. The Gaussian-like masking step is for providing a Gaussian-like masking model to process the frequency domain image to generate a frequency domain masked image. The inverse Fourier transform step is for providing an inverse Fourier transform to process the frequency domain masked image to generate a grid line removing image.

摘要： An eye center localization method includes performing an image sketching step, a frontal face generating step, an eye center marking step and a geometric transforming step. The image sketching step is performed to drive a processing unit to sketch a face image from the image. The frontal face generating step is performed to drive the processing unit to transform the face image into a frontal face image according to a frontal face generating model. The eye center marking step is performed to drive the processing unit to mark a frontal eye center position information on the frontal face image. The geometric transforming step is performed to drive the processing unit to calculate two rotating variables between the face image and the frontal face image, and calculate the eye center position information according to the two rotating variables and the frontal eye center position information.

摘要： An image processing method includes the following steps. An original image is read, and the original image includes a red channel layer, a green channel layer and a blue channel layer. A processing is performed on the red channel layer, the green channel layer and the blue channel layer, respectively, to get a derived red channel layer, a derived green channel layer and a derived blue channel layer. And the derived red channel layer, the derived green channel layer and the derived blue channel layer are combined to form a new image. The processing includes the following steps. Gradient-variations of a plurality of directions of a region are calculated. An average of the gradient-variations is calculated. A calculating procedure is provided to decide diffusion-coefficient equations of the directions, and each of the diffusion-coefficient equations is substituted into an anisotropic diffusion equation.

摘要： A color degradation compensation method is provided. The color degradation compensation method includes the steps as follows. Two images are captured by an image capturing device, wherein the two images have an overlapped area. A calculating procedure is constructed. At least one position in the overlapped area is selected and color values of a plurality of points in the position on each of the two images are read, wherein the points of each image are corresponded to the same position in the overlapped area. A ratio of the two color values is calculated. A degradation standard deviation of the two color values is calculated by the calculating procedure. The color values of the two images are calibrated to compensated color values through the calculating procedure in accordance with the degradation standard deviation.
