Hello the community,

Acutally, I use a Gige camera to capture images. The SDK´s camera allows to use OpenCV. So, I handle my image with OpenCV, and I save it with the function imwrite, with .tiff.

I need to keep all the information, so my question is : Is there information´s losses ? Because there is different types of .tiff, and some are compressed.

Thank you !

The whole point of TIFF instead of JPEG is that it usually uses lossles compression, and that is the case with OpenCV, which uses LZW compression method. (Lossy TIFF compression does exist, but those are rare, special cases).

(Nowadays PNG often replaces TIFF as it offers more control over lossless compression.)

Many thanks for you answer.

I need to use .tiff without any compression. How can I do with openCV ?

Thank you
