Sharpen image filter python
WebbHow to Use Kernels to Sharpen or Blur Images Filtering of a source image is achieved by convolving the kernel with the image. In simple terms, convolution of an image with a kernel represents a simple mathematical operation, between the kernel and its corresponding elements in the image. WebbIt can be done as follows. img_shr_obj=ImageEnhance.Sharpness(img) Where img_shr_obj is the Object for Sharpness Class of an Image and img is the Image Object from the above code. Image Sharpness Object contains a method called enhance () which is used to enhance the Sharpness. Usually, Sharpness can be enhanced according to the Factor.
