Cmake supports building outside the source tree. We will use this method to build opencv. So, create a directory in $ home as build
$ mkdir ~/build cd ~/build
We need to now create a toolchain. cmake file that we will pass to cmake so that it knows how to cross-compile.
$ vi toolchain.cmake
Add the following to toolchain. cmake and save it. This assumes that your NFS targetfs is ~ /Targetfs

Gaussian filtering is a lot of Image ProcessingAlgorithmIt is of great significance to implement the quick Gaussian filter algorithm through the most crucial intermediate step.
By reading previous documents about the Gaussian filter fast algorithm, we have achieved our own rapid Gaussian filter algorithm, which is nearly six times faster with the neon command.

This algorithm has the advantage of be

Use Java 8 functional programming to generate letter sequences
Using functional programming to generate letter sequences in Java 8 is a big challenge. Lukas Eder happily accepts this challenge and will tell us how to use Java 8 to generate ABC sequences-of course, it is not a bad way.
I was overwhelmed by an interesting question raised by "mip" on Stack Overflow. The problem is:

I am looking for a way to generate the following letter sequences:A, B, C, ..., Z, AA, AB, A
The DFA (deterministic finite automata), a deterministic finite automaton, refers to a unique next state for each state that is determined by the input alphabet, and the NFA (Nondeterminisic finite Automata) is an indeterminate finite automaton, which means that for any state, when the state obtains the input alphabet, it is possible that the resulting state is not one, but multiple, that is, a set of state
In the search local video section of Android local video player development, we can search for a local video and display the image, title, and duration of each video, of course, if you need to add other methods such as the video length and width, you can use the method in the video class. Since we have obtained the video, the next step is to decode the video. I use FFMPEG to decode the video, so this is the FFMPEG library that can be used to compile mobile phones using ndk.

The ASCII character code shown in Figure 2-1 is similar to the format in an ANSI file.ASCII has many advantages. For example, the 26-letter code is sequential (not in the EBCDIC code); uppercase and lowercase letters can be transformed from one data to another, and 10 numbers of code can be conveniently obtained from the value itself (in the Bcdic code, the character "0" is encoded behind

The Alphabetindexer constructor needs to pass in three arguments, the first argument is cursor, the second is the Sortedcolumnindex integer, and the third argument is the alphabet string. Where cursor is to pass the cursor that we have detected from the database, Sortedcolumnindex is to indicate which column we are using to sort, and
