In this process, we perform Sobel edge detection separately on the red, green, and blue color channels of the original image along both the X and Y axes. This edge detection technique helps extract prominent edge features from the image, enabling further analysis and processing. The method involves applying horizontal and vertical Sobel operators to each color channel independently, typically using 3x3 convolution kernels. The X-axis Sobel operator emphasizes vertical edges, while the Y-axis operator detects horizontal edges. By combining these directional edge maps, we can better understand the image structure and content, providing valuable information for subsequent image processing and analysis tasks. This approach allows for comprehensive edge detection that preserves color information, making it particularly useful for applications requiring detailed feature extraction from color images.
