Decide to do I’m starting with the Sobel filter for the nth time, trying to understand it from a different perspective. Basically, it detects changes in the x and y directions, then combines them using the hypotenuse formula. It’s like taking a vector in the fourth quadrant. The filter also uses some collective reference of nearby pixels — something like an average but with a different formula. If we “zoom in” on the pixel values, it essentially reveals gaps in the intensities. In short, it detects changes, magnifies them, and stores that information as a value. Now, does this value remain unique? It’s like a vector in the fourth quadrant, where the magnitude and direction depend on the surrounding pixels. So yes, it can be unique — unless the distribution changes. When the distribution changes, the direction changes too, and so we end up with different values. You can think of it like an image represented by a magnitude and direction in space. For larger images, the filter’s magni...
