چکیده

In our method for tracking objects, appearance features are smoothed by robust and adaptive Kalman filters, one to each pixel, making the method robust against occlusions. While the existing methods use only intensity to model the object appearance, our paper concentrates on multivalue features. Specifically, one option is to use photometric invariant color features, making the method robust to illumination effects such as shadow and object geometry. The method is able to track objects in real time.

Appearance Kalman tracking under severe occlusions

We propose a new method for object tracking in image sequences using template matching. To update the template, appearance features are smoothed temporally by robust and adaptive Kalman filters, one to each pixel, making the method robust against severe occlusions. The method is also robust to abrupt changes of lighting conditions, especially when photometric invariant color features are used t...

Color-Ciratefi: A color-based RST-invariant template matching algorithm

Template matching is a technique widely used for finding patterns in digital images. An efficient template matching algorithm should be able to detect template instances that have undergone geometric transformations. Similarly, a color template matching should be able to deal with color constancy problem. Recently we have proposed a new grayscale template matching algorithm named Ciratefi, inva...

Tracking and Classifying Moving Objects from Video

This paper presents a method for tracking moving objects in an outdoor environment, classifying them into three categories: single person, people group or vehicle. The proposed method integrates motion, spatial position, shape and color information to track object blobs. The blobs are segmented using the pixel-wise difference with the background, which is automatically updated by a median filte...

Similarity templates for detection and recognition

This paper investigates applications of a new representation for images, the similarity template. A similarity template is a probabilistic representation of the similarity of pixels in an image patch. It has application to detection of a class of objects, because it is reasonably invariant to the color of a particular object. Further, it enables the decomposition of a class of objects into comp...

Visual Multiple Object Tracking with Improved Feature Detection and Kinect Color Depth Map

Tracking multiple objects in real-time videos represents a challenging area in the era of computer vision. This paper proposes a new method to track the multiple objects under different environment conditions such as rotation, illumination, blurred, occlusion, and many others. In addition, the kinect color depth image processing is used to estimate the distance of the objects. The tracking of m...
