Object Tracking in Low-Frame-Rate Video
In this paper, we present an object detection and tracking algorithm for low-frame-rate applications. We extend the standard mean-shift technique such that is is not limited within a single kernel but uses multiple kernels centered around high motion areas obtained by change detection. We also improve the convergence properties of the mean-shift by integrating two additional likelihood terms us...
متن کاملLow Frame Rate Video Target Localization and Tracking Testbed
Traditional tracking frameworks are challenged by low video frame rate scenarios, because the appearances and locations of the target may change considerably in consecutive frames. Our paper presents a saliency-based temporal association dependency(STAD) framework to deal with such a low frame rate scenario and demonstrate good results in our robot testbed. We first use median filter to create ...
متن کاملVariable Frame Rate for Very Low Bit-Rate Video Coding
Motion description of objects time evolution is often bit-rate wasting even if computed at a low fixed ffame rate. Bit-rate reduction can be achieved taking advantage of the inactivity periods: in such time intervals there is no need for motion coding, as an accurate description of the scene can be obtained only considering the frame diflerence information. We propose to estimate the motion bet...
متن کاملUltra-scale vehicle tracking in low spatial-resolution and low frame-rate overhead video
Overhead persistent surveillance systems are becoming more capable at acquiring wide-field image sequences for long time-spans. The need to exploit this data is becoming ever greater. The ability to track a single vehicle of interest or to track all the observable vehicles, which may number in the thousands, over large, cluttered regions while they persist in the imagery either in real-time or ...
متن کاملFrame rate preferences in low bit rate video
A double stimulus subjective evaluation was performed to determine preferred frame rates at a fixed bit rate for low bit rate video. Stimuli consisted of eight reference color video sequences of size 352 × 240 pixels. These were compressed at rates of 100, 200 and 300 kbps for low, medium, and high motion sequences, respectively, using three encoders and frame rates of 10, 15 and 30 frames per ...
