🍿 Gaussian Kernels

There are three common ♻️ Convolution kernels in 👁️ Computer Vision, all based on the 👑 Gaussian distribution

1. Gaussian: gaussian fixed at the center, blurs image.
2. Derivative: derivative of gaussian, detects directional differences in image.
3. Laplacian: second derivative of gaussian, detects details in image (like sharpening).
