Detailed Description

Gist estimator for ``Context-based vision system...'' by Torralba, et al.

This class computes the gist vector for an input image using the technique described in section 2 of ``Context-based vision system for place and object recognition'' by Torralba, et al.

In their paper, the authors apply 24 filters to the image (6 orientations, 4 scales) and average the results over 4x4 grids to get a total of 384 texture features which comprise the gist vector. This class computes and returns this vector of 384 numbers.

Constructor & Destructor Documentation

GistEstimatorContextBased::GistEstimatorContextBased	(	OptionManager &	mgr,
		const std::string &	descrName = "GistEstimatorContextBased",
		const std::string &	tagName = "GistEstimatorContextBased"
	)

The constructor expects to be passed an option manager, which it uses to set itself up in the INVT simulation framework.

Member Function Documentation

Image< double > GistEstimatorContextBased::getGist

(

)

[inline, virtual]

This method returns the gist vector computed for the input image. The gist vector consists of 384 numbers that are obtained by averaging the pixel values in each of the 16 subimages of each of the 24 filteration results.

Implements GistEstimator.
