image header info in image processing

[manojb]

Hello Friends,

I am new to image processing; I am looking for a image which should have a header and pixels.
Example: if I take JPEG header which is having 10 bytes and the end of the image pixels its have one or two bytes, which is the ending byte. (I don’t want like that of image header)
Image Header + pixels only,
Y because I am asking is that I need to process the pixels to some process, and re-image it. I donot want to search for end of image pixels
So help me out,

Thanking u

Below is a 16x16 pixel picture of Mona Lisa in jpeg with 85% compression factor and all unnecessary markers removed. It ought to contain 4 jpeg blocks. Maybe it helps?


Your question is slightly unclear on what exactly you are looking for.

Hex dump btw..

thank for the reply, i want the pixels of the image, for some process. but i do not want the header in the first part and the last part. if u see the image in the textpad JPEG is having the the header in the first then pixels then the end of header.

so i want a image format with the only header (how many bytes its having) and the pixels for my process.

 

[eagledot]

What is your process?
Define what you mean with "header".
Header is in the beginning of the file.
The file offered has only the header and the pixels. Otherwise it would not be an image.

You are still very unclear on what you want.

JPEG Header Format

[TrickyDicky]

why not strip the header out yourself?
or use a more conveinient format like bitmap (where there is not compression).

 

[manojb]

I understood the image format n header, Now i want to no about the video header info for video processing, like BMP header it has only first 54 bytes has a header like tat i want the video header should be simple.
