Generate the Fight network Gan currently has a very good application in image generation and confrontation training, this article aims to do a simple tf wgan-gp mnist generation Tutorial, the code used is very simple, and we hope to learn together. The code is as follows: The use of the environment: TensorFlow 1.2.0 GPU acceleration, the CPU is also OK, is very slow, you can change the batchsize small, with a good CPU training some, and by the way to create image code department to change, My

Another need to calculate the size of the output after the convolution, from the following figure is very good to understand, with the formula directly calculated. where n is the input image of the size,f is the size,stride of the filter is the sliding step.And then from the last example in the diagram above, we can see that when the stride

In one call to Glmultidrawarraysindirect (), you can distribute a total of drawcount separate drawing commands that are in line with the parameters in the Gldrawarraysindirect ().

The first module in main path: The first convolution layer conv2d, F1 F 1 f_1 filters, size = (1,1), stride= (1,1), padding set to "valid", named Conv_name_base + ' 2a ', s Eed=0 is used for random initialization of parameters. The first batchnorm is normalized along the channel direction, and the name Bn_name_base + ' 2a ' Relu activation function is not required
convolution)
For narrow convolution, the convolution is done from the first point, and each window slides a fixed stride. For example, the left part of the following figure is a narrow convolution. Then notice that the more times the edges are being rolled down the less. So there is a wide convolution method, can be seen in the convolution before the edge with 0 supplements, common in two cases, one is full complement, into the right part of the figu
Bitmapsource is the most basic type of WPF images. It also provides two pixel-related methods: copypixels and create. You can use these two methods to cut a part of an image, similar to the croppedbitmap type of another bitmapsource.
The copypixels method needs to initialize the array in advance and specify a rectangle (int32rect type) to indicate the size of the occupied area. Calculate the number of bytes (STRIDE parameter) and offset (offset p
Both iplimage and bitmap are memory graphics representation methods. The former is the opencv open-source visual library, and the latter is the GDI +. If the opencv library is used in VC, the conversion between the two is likely to be used.
If you search for these two formats on the Internet, it is likely to find a version with Memory leakage (such as http://blog.csdn.net/jtujtujtu/article/details/3734722), so here provides a version without memory leakage for your reference.

AlgorithmIn the past, when using the uint pointer to access a 32-bit argb bitmap in C ++, the offset is exactly one pixel, so "++" instead of "+ = 4" is used directly ". Similarly, "I * stride/4 + J" instead of "I * stride + J" should be used for direct access using coordinates ". But transfer to C #

The receptive field is a kind of thing, from the angle of CNN visualization, is the output featuremap a node response to the input image of the area is to feel wild.For example, if our first layer is a 3*3 core, then each node in the Featuremap that we get through this convolution is derived from this 3*3 convolution core and the 3*3 region of the original image, then we call this Featuremap node to feel the wild size 3*3If you go through the pooling layer, assuming that the

General pooling because each pooled window is not duplicated, sizex=stride.The most common pooled operations are the average pooled mean pooling and Max pooled Max pooling:Average pooling: Calculates the average of an image area as a pooled value for that region.Average pooling: The maximum value of the selected image area as the value after the zone is pooled.2.
