This will cause the text Renderer to render "hell" first, then "o", then "w", then "o", and then "rld ", A total of five drawing commands were executed and five texture bindings were executed. In fact, both of them were required twice. The current Renderer first draws "hell w rld" and then draws two "o" in one piece ".Optimize texture upload

Grayscale of color image
The 24-bit color image is represented by 3 bytes per pixel, and each byte corresponds to the brightness of the R, G, and B components (red, green, and blue). When 3 components do not want to be simultaneously displayed as grayscale images. Here are three conversion formulas:

Since Deep Q-network are trained on the raw pixel values observed from the game screens at each time step, [3] finds that re Move the background appeared in the original game can make it converge faster. This process can being visualized as the following figure:

First of all, your should avoid storing or transferring raw images to your phone; Its all better to convert them to a compressed format such as PNG or JPG on your PC, and deploy this artwork to the Dev Ice.However, if for some unusual reason the really want to the load raw images, here are an approach:1) C
the specified subset of the source bitmap.
Static Bitmap
CreateBitmap (int [] colors, int offset, int stride, int width, int height, Bitmap. Config config)
Returns a immutable bitmap with the specified width and height, with each pixel value set to the corresponding value in the colors array.

to improve the structure of CNN proposed. Like what:
Use smaller receptive window size and smaller stride of the first convolutional layer.
Training and testing the networks densely over the whole image and over multiple scales.
3. CNN Configuration Principals
The input from CNN is a 224x224x3 image.
The only preprocessing before the input is the minus mean value.

input neurons on the original. Because these neurons want the same feature, they are filtered by the same filter. Therefore, the parameters of this 10x10 connection on each neuron are a hair-like one. Does it make sense? In fact, this 10x10 parameter is shared by all neurons on this feature map. This is the weight sharing Ah! So even if you have 6 feature graphs, only 6x10x10 = 600 parameters that need to be trained. (assuming that the input layer has only one picture)Further, this 10x10 parame

However, it is inconvenient to directly use the Threading class. For this reason, Parallel computing classes such as Parallel are added in several later versions of C #. In actual encoding, Partitioner is used. create method, we will find that this class is particularly suitable for Parallel Computing in image processing. For ex

Some companies are most concerned with customer data, and some are their own employee data, because their respective businesses are different. IDC is related to the customer's data security. The customer's security is the company's security, and whether a company can win the customer's trust. When the data is well planned, we have a rough understand

Ii. Color Removal
This function completes the grayscale processing of the image. Our basic idea is to take the average value of the three color components of each pixel point. However, due to the sensitivity of human eyes, the effect of completely average value acquisition is not good.
Program In, I took three parameters with the best results:. 299,. 587,. 114. However, it should be noted that in GDI +, the image storage format is BGR rather than RGB, that is, the order is blue, green, and red.

Use bitmap.LockbitsThe bitmapdata method can be used to obtain bitmapdata. bitmapdata. scan0 points to the base address of the bitmap data part. Bitmapdata. stride provides the number of bytes occupied by each row in the image. Pay attention to bitmapdata. stride is not equal to bitmapdata. width for the following reasons: (1) bitmapdata. w
