    Hi All,

    how to resize an image with the width more than 1334 pixels by IPIPE? how to split the image in horizontal to several blocks and resize them respectively using IPIPE?

    Could you please give me some reference source code with it? Thanks in advance.

     

    Best Regards,

    Jeff,

    Unfortunately, we do not have any reference source code to proivde.  However, this should be fairly trivial. Using DMA (optional but best), you need to copy image into two intermediate separate input buffers of 1334 / 2 by height; you will use these intermediate buffers to pass thru resizer.  At the output end, you will need to copy separate images back into a single image (again using DMA should be best).  As you can see, all these boils down to is moving memory around.  All you need to know is your desired input and output video resolution which you should know already.
