I want to upscale an image by 2 times. If the scaled image width and height are W and H respectively, then i need to create another image from the scaled image with width x height = 2W x 2H.

But I am unable to get any process to do that.

Please help.

Only DSS M2M path can do upscaling. can you refer to below link for adding dss mem in vision apps?

Hello Brijesh,

Thanks for the Info. We still don't have an idea about how to do the upscaling of the image. Can you please provide us with some examples on the same as how to proceed with the same? Code examples will be preferable.

Hello Sambeet,

Unfortunately, there isn't any example in SDK demonstrating upscaling. I would suggest referring to above example, and make changes in the example for upscaling. You would most likely have to set different output image size than input image size to enable scaling.
