JPEG image file creation to be recognized by OS

Question

I have applied JPEG baseline compression algorithm by writing each step in matlab. Now, I have the JPEG compresses image data in binary form and the header to be appended. Please tell me how to make a file that would be recognized as JPEG file by OS. Should it be binary file or what is the process.?

Answer 1

You are going to need to read two thing:

1) The JPEG standard

2) The standard for some file format (e.g., JFIF, EXIF).

You are going to need to have a JPEG file header (see file format standards). You are going to have to create DHT, DQT, SOF, and SOS markets for the compressed data (JPEG standard).

All of the data is in binary format. You have to remember to convert FF values in the compressed data stream to FFFF.
