👉 Intergradient is a concept in image processing and computer vision that describes how the gradient of an image changes with respect to its intensity. It's often used in image restoration, where it helps in identifying areas of brightness or contrast improvement. Intergradients are calculated using a method called Sobel's derivative operator, which involves calculating the gradients of each pixel's position along two perpendicular lines. These gradients are then summed up to get an overall value that represents the intensity change in that area.
