bins N can adjust the image smoothness. the Radius of the template is used to adjust the degree of watercolor painting.The preceding algorithm improves the efficiency by using the fast mean Filtering Algorithm for template traversal.The Code is as follows:Private Bitmap OilpaintFilterProcess (Bitmap srcBitmap, int radius, int smooth){If (radius = 0)Return srcBitmap;Smooth = smooth Smooth = Math. Max (1, smooth );Bitmap a = new Bitmap (srcBitmap );Int w = srcBitmap. Width;Int h = srcBitmap. Heig
of each row. I am the pixel of the whole row, 1 is to select only one column.Colors [J] = color. RGB (255-color.red (colors [J]), 255-color.green (colors [J]), 255-color.blue (colors [J]);Obtain the R, G, and B channel values respectively, and then encapsulate them into a new color value. In fact, the effects of this instance can be achieved in multiple ways, you can use getpixel (int x, int y) and setpixel (int x, int y, int color) to implement, you can also use getpixels (INT [] pixels, int o

program that reads and writes elements and measures average time. By changing the size of the array, it is possible to infer the size of the cache, the size of the block, and some other properties.The modified version of my program is in the cache directory of this book repository.The core part of the program is a loop:iters = 0;do {SEC0 = Get_seconds ();for (index = 0; index } while (sec The internal for loop iterates through the array. Limit determines the range of array traversal.
between the lockbits method and the unlockbits method, many methods cannot be called, and sometimes it is inconvenient or even cumbersome. For example, if you want to display or save the scanned lines of image data multiple times, you have to call these two methods repeatedly; in addition, images with a bitmap format lower than the 24-bit format cannot be locked to 24-bit or 32-bit data for operations (we mostly use 24-bit or 32-bit pixel scanning lines for image processing. You can use some ti

1, convolution layer: Is the convolution layer, which is the core layer of convolutional neural Network (CNN). Layer Type: Convolution Lr_mult: The coefficient of the learning rate, the final learning rate is the number multiplied by the BASE_LR in the Solver.prototxt configuration file. If there are two Lr_mult, then the first one represents the weight of the learning rate, the second one indicates the bias of the learning rate. The learning rate of the general bias is twice times that of the w

, 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.
