GPU Coder won't accept ACF Object Detector model

3 visualizzazioni (ultimi 30 giorni)
We have a need to identify specific objects in binary (BW) images. I successfuly trained an ACF Object Detector model to run on CPU hardware, but we need this code to run on a GPU based system. However the MATLAB GPU Coder rejected the ACF Object Detector model with this error message:
Error determining type for input '<detector-name>: detector'.
Class acfObjectDetector is not supported by coder.Type as it is a handle class.
Does the GPU Coder accept any of the MATLAB image detection/analysis tools like YOLO or CNN?

Hi John,
Currently we are not supporting the feature for Code Generation for the ACF Detector Function. The error shows up since handle class objects are not supported as input or output from mex files.
As a workaround, you can convert the object into a struct and use the toStruct function to pass the acfObjectDetector object into generated code. Please refer to this link for more information.
For generating code for object detection using YOLOv2, one can refer to this link.
Hope this helps!
