3. Matlab vectors use indexing in order to identify the location within the vector, here, your signal x. . Load a sample image from skimage (pip install scikit-image) from skimage import io,data img = data.camera() io.imshow(img) You will see . Because Numpy's convolve only works for 1-D array, so I will use the convolve function from OpenCV package. Depending on what you want to do, you can either average across the channels to get a single audio vector (like a mono) as xAvg=mean(x,2);, or you can choose a specific channel to work with like xChannelK=x(:,k);, where 1<=k<=M is the chosen channel.
