jevois::dnn::PreProcessorForPython Class Reference

#include <jevois/Core/PythonModule.H>

Pre-Processor interface expose to the python side.

This wrapper is passed down to the process() function of a python post-processor, it provides a python-friendly interface to b2i(), blobsizes(), etc

b2i()

cv::Point2f jevois::dnn::PreProcessorForPython::b2i	(	float	x,
		float	y,
		size_t	blobnum
	)

Convert coordinates from blob back to original image.

Given coords x,y should be in [0..w-1]x[0..h-1] where w,h are the blob's width and height. This is useful to convert detected boxes back into original input coordinates.

Definition at line 629 of file PythonModule.C.

blobs()

boost::python::list jevois::dnn::PreProcessorForPython::blobs

(

)

const

Access the last computed blobs (or empty if process() has not yet been called)

Definition at line 623 of file PythonModule.C.

blobsize()

cv::Size jevois::dnn::PreProcessorForPython::blobsize

(

size_t

num

)

const

Access the width and height of a given blob, accounting for NCHW or NHWC.

Definition at line 626 of file PythonModule.C.

getUnscaledCropRect()

cv::Rect jevois::dnn::PreProcessorForPython::getUnscaledCropRect

(

size_t

blobnum

)

Get unscaled crop rectangle in image coordinates.

This is useful to display an image overlay on top of the input image.

imagesize()

cv::Size jevois::dnn::PreProcessorForPython::imagesize

(

)

const

Access the last processed image size.
