Image is in the range [0-1].I tried to use Mat img=imread(filename,CV_LOAD_IMAGE_COLOR); But the rows are 0 and cols are 0 and channels as 3. So how to access it properly. when i'm using CV_LOAD_IMAGE_ANYDEPTH error is coming.

Can you please confirm your bit depth? i.e is it floating point [0.0 - 1.0] or bool (Binary) [0 or 1] ? There is no binary data format in opencv! You can use 8UC instead!

In matlab it is showing as single bit image

Image we only computed using ERDAS software. Image is converted to TOA(Top of Atmospheric reflectance)... Stored as tiff format

Bit depth is [0.0-1.0]

opencv support for weird tiff formats is unfortunately very sparse.

maybe you 'll have to fall back to use libtiff directly (w/o imread() wrapper)

Unable to use libtiff properly..So is there any other way to access it
