[Scilab-users] scilab and tif-files

[Chin Luh Tan]

Hi, 



I remembered I was having some issue on reading the tiff file which was trying to read in different bits per pixels such as 12 bits (for a type of CCD camera) , that's why created the tifread for reference as I believe it there would be much more different standard of images/data which are not covered by imread. (for e.g. I just came across YUV video which need to be read by Scilab basic IO)



As for standard RGB image (8-bits per channel), it should be fine, you might want to send a sample (upload somewhere) and let us have a look.



Thanks.



rgds,

CL

Dear experts,



I do have a tif-file....in fact: lot's of them and of different size.



Pixel values are:  

- red

- green

- white

- black



Now, I want to convert these files in Black/white images, such as:



- red pixels --> black

- green pixels --> white

- black pixels --> black

- white pixels --> black



in other words:    Only the green pixels are of interest.



Now, as I use IPCV:



- imread()...does not handle tif-files correctly



--> it does read the files, but the output is a boolean-matrix......that doesn't help



- tifread()...does only handle  images with size 
1024x1024 ... doesn't help



Is there a way to read TIF-files into Scilab and keep the R-G-B-channels?





Thank you,

Philipp
