converting binary image (8 bits) into Decimal image?

[wady1]

How to convert a binary image (8 bits) into decimal image? Would it be bin2dec() is the function to be used? Any example please?
Thank you in advance for your help.

what you mean by binary to decimal?

An image is in binary format( a matrix of 8 bits) that we need to be converted into Grayscale format image.

Yes. But open to use C or C++ if needed, but matlab is what I am using now.
Thank you.

HI THERE
It sounds difficult.There are many image converter which supports to convert image effecively.Maybe you can search it.If there is any powerful one.i 'd also like to have a try.

There's a number of ways to do that based on the coder's preference.

Pseudo-codish, take with a grain of salt. I only just got out of bed.

// This is just a simple converter that takes a binary string and converts it to a char array
#include <string.h>
#include <math.h>

int i = 0;
int length = strlen(BINARYINPUT) / 8; // I have no clue how your original data is saved.
unsigned char output[length];
unsigned char out = 0x00; // It looks trashy to me if a loop declares a value every iteration
do {
  out = bin2dec(BINARYINPUT.substr(i*8,i*8+8));  // 8 chars per hex value, so pos of the substring is i*8, length is i*8+8
  output[i] = out;
  i++;
} while (i < length);

As to saving it as a .BMP file, I dunno, because I have no idea what format your original data is in. There are probably more than Microsoft is willing to list. If you know your pixel format and this binary stream is just pixels, i.e. no header information, then you can save it as a .RAW and use FFMPEG or some image processing tool to convert it to .BMP afterwards.
