A linear filter function NeuralNetLN is now added to NeuralNet plugin. This function can process images where a linear relation from input to output exists. Center is input, on right is processed by VFan and a small part of it used for training and on left is processed by NeuralNetLN. The images at this scale appear identical but at full scale there were differences. Most noticeable was in the rectangle inside the inverted triangle to the right of the subjects head. Some faint details seen in VFan filtered image were not seen in NeuralNetLN processed image. I have also tested with GaussBlur (part of ColorIt plugin) with good result. The script used is Code:
