Quizplus · Accepted Answer

Convolution is a mathematical operation that modifies pixel values in an image by applying a weighted kernel or filter. It involves multiplying each pixel value in the image with the corresponding value in the kernel, summing up the products, and replacing the original pixel value with the result. This process is used in various image processing tasks, such as edge detection, blurring, and noise reduction. Deconvolution, on the other hand, is the process of reversing the effects of convolution, which is generally a more complex and challenging task. Calculus and interpolation are mathematical concepts that relate to different aspects of approximating and analyzing functions, but they do not directly involve modifying pixel values in an image. Therefore, the best choice for the given question is A) Convolution.
