This PR introduces block-quantized versions for most of the opencv_zoo models.
All the models have been quantized using a block size of 64, as this configuration demonstrated good performance empirically.
Additionally, the block quantization tool has been enhanced to handle more cases:
constant
in ONNX (previously, it only supportedinitializers
).Finally, the benchmark tool has been modified to support block quantized models.
The following table contains block quantization statistics of the quantized models
The tables below summarize the metrics change between the original fp32 model, block quantized and int8 quantized version:
The following models haven't been quantized:
