Block matching algorithm python github
WebK-Nearest Neighbor Matching is to classify a new input vector x, examine the k-closest training data points to x and assign the object to the most frequently occurring class. Optionally, we give closer points larger weights and more distant points smaller weights. Common value for k is 3 or 5. Web101 - What is block matching and 3D filtering (BM3D)?
