It is sufficient to fill/clear only one of these. It enhances the grayscale transition of an image, which is the opposite of image smoothing. For example, for Figure 2.3.1, the response R to the template is: In mathematics, this is known as element-wise matrix multiplication. labels will be returned, instead of only the most likely This is fastest.

As you can observe, shifting the training loss values a half epoch to the left (bottom) makes the training/validation curves much more similar versus the unshifted (top) plot. It can also suppress horizontal or vertical stripes that were created by scanning an image line by line. that touch the outside of the image are removed.
