Constructor.

Creates an empty image patch, which can be set later using setImage.

Member Function Documentation

void ImagePatch2::setImage	(	const cv::Mat &	image,
		int	setData = 1,
		int	setIntegral = 1,
		int	setSqInt = 0,
		int	setTInt = 0
	)

Sets the ImagePatch to contain this image's data.

Copies the whole image, so any cropping, converting, and resizing must be done prior to calling setImage. The image must be of type IPL_DEPTH_8U (8-bit, unsigned integer), with a single channel.

Parameters:

image	The image we want to represent.
setData	Copy the image data. This takes some memory, and is often not needed if we are only using integral based features. However, it is necessary for visualization of ImagePatch data, and may be useful for other feature types.
setIntegral	Compute the integral of the ImagePatch. This is required to apply BoxFeature to the ImagePatch.
setSqInt	Compute the square integral of the ImagePatch. This is required to apply features that rely on variance.
setTInt	Compute the tilted integral of the image patch.

void ImagePatch2::setImage	(	const cv::Mat &	image,
		cv::Rect	ROI,
		int	setData = 1,
		int	setIntegral = 1,
		int	setSqInt = 0,
		int	setTInt = 0
	)

Sets the ImagePatch to contain this image's data contained in ROI.

Any converting, and resizing must be done prior to calling setImage. The image must be of type IPL_DEPTH_8U (8-bit, unsigned integer), with a single channel.

Parameters:

image	The image we want to represent.
ROI	The region of the image we want to represent.
setData	Copy the image data. This takes some memory, and is often not needed if we are only using integral based features. However, it is necessary for visualization of ImagePatch data, and may be useful for other feature types.
setIntegral	Compute the integral of the ImagePatch. This is required to apply BoxFeature to the ImagePatch.
