, in fact, all the filter and all the local area of the dot product operation, of course, this result also needs to be re-reshape to the desired output size. This process also explains why the parameters of a neuron can be stored in a filter and why the network layer is called a convolution layer. 2.

same time; second, the memory data is copied to the data, after processing, copying the array data will reduce the memory speed. As an improvement, we should make full use of lockbits. In lockbits, there is a mode in lockmode: imagelockmode. userinputbuffer. In this mode, the user needs to apply for memory first, and then fill the image data in the relevant format such as this memory. In this way, you can define an array and then fill the image data in this array to avoid the time required to c

transparency of the layer to 50%. The partial enlargement result is as follows: With this effect, you can easily draw a conclusion: The center of the Offset is centered on each pixel. The four offsets are symmetric in the center, arranged in a circular direction of 45 degrees oblique, and 45 degrees horizontal and vertical offsets, respectively. The offset is 4 pixels. We can guess how to overlay the data by taking the average value of the accumulated value after four offsets. To solve this pr
