This article describes how to calculate the gray histogram of an image and perform binarization on the image, the binarization threshold values described in this article are all set by yourself. The threshold values set by yourself are often inaccurate, and the optimal threshold values for different images are different. So can the computer calculate the optimal threshold of the image? The answer is yes. Ne
Calculate the date after the specified business day. This function is used in recent projects to calculate the date after N working days. now we can solve the problem by thinking of the following solutions. This indicates that the workday is still used in the recent project according to the national regulations to calculate the date after N working days. now I th
how to find all of its child nodes, then we know that because you make a maximum of M-decisions at each stage (there will be fewer stone numbers than m decisions)So through M we can find the state of its successors, because each time we only use the M state, so we only have this m state, each iteration can beHow do we iterate? We are going to analyze the recursive tree, each time this m state is what state (I have to use which M state), this problem is just the regular, constantly used to

It turns out that it is not a problem to calculate the date difference between the two time points until one day .... One of the developers I once coached asked me for advice. I didn't think it was very difficult. I tried to use the calendar/gregoriancalendar class for computation. It seems that the code is too complicated and I gave up. I tried for half an hour and finally came up with a sentence and wrote it to him on MSN. At that time, I felt that
The test is as follows:

JOJ 2042 is a program comprehension question, which provides a wonderful program for calculating x ^ 3. The principle is as follows:
It can be seen from the above that the power function increases by 6 for the first time, and its initial value is 1. Therefore, you can write the program to calculate the Cube as follows:
Int f (x ){
Int c = 0, d = 1, e = 6;
While (x --){
C + = d;
D + = e;
E + = 6;
}
Reutnrn c;
}
Similarly, based on this idea, you can

Prerequisites
All models must be exported to the. OBJ file format.
If you want to calculate from a separate material, you need to export the low mode with material.
Note:You can find the polybump application in the SDK installation directory.

\ Tools \ polybumpapplication64.exe
In 64-bit operating system, crytekrecommends using polybumpapplication64.exe, which can process more polygon During computation.
