چکیده

This paper deals with the problem of tracking an object from a sequence of images captured from a camera moving towards the object. Many conventional image based trackers trace key reference points over an image sequence using simple correlation processes 1]. However, the presence of noise and the magniication of image features as the camera approaches the object may cause a tracked point to drift. This paper introduces an alternative technique based on tracking regions formed by image segmentation. A region template of the target is acquired in the rst frame and correlated over segmented images in future frames. The new technique produces signiicant reductions in drift rate and results have been obtained for real forward looking infrared (FLIR) images. This paper then discusses the advantages of integrating the new technique with a conventional point correlation based tracker.

Evaluation of Similarity Measures for Template Matching

Image matching is a critical process in various photogrammetry, computer vision and remote sensing applications such as image registration, 3D model reconstruction, change detection, image fusion, pattern recognition, autonomous navigation, and digital elevation model (DEM) generation and orientation. The primary goal of the image matching process is to establish the correspondence between two ...

Correlation techniques in adaptive template matching

The use of correlation as a measure of similarity between two signals is a well known technique. Correlation is commonly used in stereo vision to solve the correspondence problem. In this context the aim is to nd the position of a point in one of the two images of a weakly calibrated stereo pair which corresponds to a point in the other image. Template windows are chosen from the rst image as 2...

Correlation-based visual odometry for ground vehicles

Reliable motion estimation is a key component for autonomous vehicles. We present a visual odometry method for ground vehicles using template matching. The method uses a downward facing camera perpendicular to the ground and estimates the motion of the vehicle by analyzing the image shift from frame to frame. Specifically, an image region (template) is selected and using correlation we find the...

Tracking Targets in FLIR Images by Region Template Correlation

This paper deals with the problem of providing missile guidance information by tracking a target object from a sequence of image frames captured from a forward looking in-frared (FLIR) camera mounted inside a missile moving directly towards the target. Many conventional image based trackers trace key reference points over an image sequence using simple correlation processes. However, the presen...

Template Matching based Eye Detection in Facial Image

Eye detection is a pre-requisite stage for many applications such as human–computer interfaces, iris recognition, driver drowsiness detection, security, and biology systems. In this paper, template based eye detection is described. The template is correlated with different regions of the face image. The region of face which gives maximum correlation with template refers to eye region. The metho...
