Is Huffman compression methode applicable to create 16 Bit gray scale PGM image

[manojkp89]

Hi,

I created 16 bit gray scale pgm image from set of intensities values,but the size of image was too large.So i used Huffman compression algoritham,but it was failed(full black image).

Is it possible to apply Huffman compression algoritham in pgm image creation?

Regards,

Hi Manoj,

to answer those questions (totally unrelated to LabVIEW) you might consider reading Wikipedia or use a search engine like G**gle.

Those old PBM/PGM/PPM formats usually don't support compression to keep things simple.

You may put such a file into a ZIP container afterwards for data transfer reasons, but you need to unZIP them before working with the images in your image processing tool.
