Crop and resize image

[yslavcom]

There is an example with crop done with software at
https://github.com/AxisCommunications/acap-native-sdk-examples/tree/main/object-detection

However, my case is a bit different, I want to crop bounding box around a detected object and resize it to a specific model input size and for every frame the crop might be of a different size. Is there a chance of doing it with hardware support using larod library or anything else rather then doing it in software?

Thank you

As far I know you could just change the job params before execution

Thank you for the suggestion, I can crop a region in image, but the resulting image is distorted
original:

croppped & resized:

Both are expected to be rgb-interleaved

Eventually, I was able to do the crop in software by simply copying the bytes from one vector into another and resizing using the larod APIs.

It would be great to also just crop an image using the larod API for greater efficiency. Is there any example please?

basically crop happen here

acap-native-sdk-examples/object-detection/app/object_detection.c

Line 490 in 90f695a

syslog(LOG_INFO, "Calculate crop image");

Thank you for that! Why is there a crop purely in software for GRB interleaved here? https://github.com/AxisCommunications/acap-native-sdk-examples/blob/90f695ab536f865a65446bbc4f2797d9a6aee153/object-detection/app/object_detection.c#L944 Thank you, Iaroslav
