In our example, we have . 6. Application to Image Denoising Let’s see how PCA can reduce the noise in an image. We start with a noiseless image and add a Gaussian noise with a variance equal to . The image is treated as a 2D matrix divided into patches. Our PCA is performed on ...
I'm new to PCA and I would like to learn the outcome of pca function. I have read the document and checked others works but I'm a bit confused on how to related the results (wcoeff,latent,explained) to the original data. For example, I'm using the example from the document as be...
