AI Technical Summary

Problems solved by technology

However, traditional image patch-based methods tend to suffer from drifting template problems (such as accumulating errors in template updates leading to tracking failures) and may be sensitive to partial occlusions
Some see feature-based methods as insensitive to partial occlusions, but have traditionally proven less useful for tracking objects that undergo large pose changes

Abstract

A method, apparatus and computer program product are provided that may enable devices to provide improved object tracking, such as in connection with computer vision, multimedia content analysis and retrieval, augmented reality, human computer interaction and region-based image processing. In this regard, a method includes adjusting parameters of a portion of an input frame having a target object to match a template size and then performing feature-based image registration between the portion of the input frame and an active template and at least one selected inactive template. The method may also enable switching the selected inactive template to be an active template for a subsequent frame based at least on a matching score between the portion of the input frame and the selected inactive template and determine a position of a target object in the input frame based on one of the active template or the selected inactive template.

Description

technical field [0001] In general, embodiments of the invention relate to computer vision, and more particularly, to apparatus, methods and computer program products that enable object tracking using online template switching and feature adaptation. Background technique [0002] In today's world, electronic devices are becoming ubiquitous. Whether used for business, entertainment, communications, security, or a variety of other purposes, the capabilities of such devices continue to expand. As evolutions have been made with respect to processing power, rendering techniques, memory, power consumption, and others, various applications have been developed to take advantage of the expanded capabilities of computing devices. However, the expansion of the capabilities of such devices also introduces a new set of challenges when looking to go further and develop new applications. [0003] One area where the use of electronic computing devices presents new challenges involves compu...
