The training convolution network on the thinning image is 21 higher than the newest result on the Mpiigaze dataset. 3.1.4 Application Details Refine the network, rθ, as a residual network. Each residual network module contains 2 convolution layers, each containing 64 feature graphs, as shown in Figure 6.The 3x3 sized filter convolution 55x35 the size of the input image, outputting 64 feature graphs. The output passes through 4 residual modules. Finally, the output of the last 1
preparations are ready, we can build the network. ResNet V2 is relatively complex, in order to reduce the amount of code to build a layer of ResNet v2, This article will take the auxiliary library to implement. The following code is based on my understanding of the ResNet network and existing resources ("TensorFlow combat" and so on) sorted out, and according to their own understanding added comments.

Output matrix called convolution feature or feature map Think about how this is done, we slide the orange matrix (also called ' Stride ') on the original image (green) 1 pixels, 1 pixels, and in each position we multiply the corresponding elements of the two matrices to get an integer, which is the element of the output matrix (pink). Note that the 3x3 matrix is only "seen" at a time as part of the image input. The 3x3 matrix is also calle
The bitmap class providesLockbitsAnd correspondingUnlockbitsMethods which enable you to fix a portion of the bitmap pixel data array in memory, access it directly and finally replace the bits inBitmap with the modified data.LockbitsReturnsBitmapdataClass that describes the layout and position of the data in the locked array. The bitmapdata class contains the following important properties; Scan0The address in memory of the fixed data array StrideThe width, in bytes, of a single row of pixel d

This is because windwos requires that the length of a row to be scanned must be a multiple of 4 (in bytes). If not, it must be completed. Calculation formula: stride =

The bitmapdata class includes the following important attributes: Scan0: Address of the data matrix in the memory. Stride: the row width in the data matrix, in bytes. Several bytes may be extended, which will be described later. Pixelformat: pixel format, whi
