Class Description

class detect_features_process : public sprokit::process

Detect feature points in supplied images.

Stabilizes a series of image.

\process This process generates a list of detected features that can be used to determine coordinate transforms between images. The actual rendering is done by the selected detect_features algorithm implementation

\iports

\iport{timestamp} time stamp for incoming images.

\iport{image} Input image to be processed.

\oports

\oport{feature_set} Set of detected features for input image.

\configs

\config{feature_detector} Name of the configuration subblock that selects and configures the feature detector algorithm

\iports \iport{timestamp} \iport{image}

\oports \oport{feature_set}
