phixel

phixel is a small snippet of c++ opencv code to help you create a pixelized picture composed with other pictures by yourself.

The running result is just like below:

gray mode:

color mode (may be a little green, cause my test pictures contains too many vegetables):

easy to use

prepare

Because this file is written with c++ opencv. It is a must to have the opencv c++ installation on your computer. You can learn about installing opencv from here.

And I chose to use opencv with gcc and Cmake. You can learn about it from here.

Test environment:

ubuntu 16.04
c++ opencv 3.10

let's phixel

To get the code and test running:

NOTE: For the image file folder may be a little bit large, if it is a worry, just download the txt and cpp files. :)

git clone https://github.com/lawlietxxl/phixel
cd phixel
cmake .
make
./phixel

If you can see "The file has been saved to" somewhere after some outputs, congratulations, you are ready to use it.

Get into the phixel.cpp file, you can see 2 variables defined before the real code starts.

>phixel.cpp

#define PIXEL_LENGTH 20
#define SINGLE_PIC_LENGTH 20

PIXEL_LENGTH means the length when pixelizing the picture like what the picture shows.

SINGLE_PIC_LENGTH means the single picture length when filling the pixelized picture. Every single picture will take one pixel of the pixelized picture.

NOTE: the code will cut the filling pictures into square.

Change the 2 variables as you like. But take care of the memory, cause if you change the SINGLE_PIC_LENGTH to a very large number, the memory might be out of use.

Then remake the project.

make

how to use

It's very easy to use it.

cd /the/project/path
./phixel <imageName> <folderPath> <writePath> <mode: gray/color>

ImageName: the picture you want to phixelized.
folderPath: the candidates waiting to be filled into the new picture.(NOTE: Please don't let the total size be too large.)
writePath: the new picture's path/name.
mode: just type in gray or color. Nothing more!

Please enjoy!

NOTE: The test file comes from the web and the candidates come from ImageNet.
