What are the color formats supported for image resize/scaling?

Can I resize a YUV image using  FASTCV?

Hi,

Image resizing APIs in FastCV work for greyscale images only. Some APIs (mostly for color conversion with a few exceptions) support color images.

Cheers,

Hi,

Most FastCV APIs take grayscale image input only. For downscaling YUV image you can use the following two APIs:

fcvScaleDownMNu8

fcvScaleDownMNInterleaveu8
