Patent number: 9959485Abstract: An image pattern recognition method detects a pattern in a sequence of video images or individual images from detected interest points. Feature vectors are extracted with video data from video regions around the interest points. A forest of decision trees is used to compute a set of bin values in histograms with bins corresponding to leaf nodes of the decision trees. Each bin value is a sum of contributions computed for individual interest points. Non-binary decision functions are used to compute the contributions and node dependent scale values are used to compute the arguments of the non-binary decision functions. The node dependent scale values may be computed from standard deviations of feature values found for the nodes, multiplied by a factor that is common to the nodes. This factor may be adjusted by feedback so that it can be set differently for different detection classes.Type: GrantFiled: December 20, 2013Date of Patent: May 1, 2018Assignee: Nederlandse Organisatie voor toegepast-natuurwetenschappelijk onderzoek TNOInventor: Gerardus Johannes Burghouts
