A Modified Distortion Measurement Algorithm for Shape Coding
Efficient encoding of object boundaries has become increasingly prominent in areas such as content-based storage and retrieval, studio and television post-production facilities, mobile communications and other real-time multimedia applications. The way distortion between the actual and approximated shapes is measured however, has a major impact upon the quality of the shape coding algorithms. I...
متن کاملFabrication of New 3D Phantom for the measurement of Geometric Distortion in Magnetic Resonance Imaging System
Introduction: Geometric distortion, an important parameter in neurology and oncology. The current study aimed to design and construct a new three-dimensional (3D) phantom using a 3D printer in order to measure geometric distortion and its 3D reproducibility. Material and Methods: In this study, a new phantom ...
متن کاملRate-distortion optimal skeleton-based shape coding
We present a new shape-coding approach, which decouples the shape information into two independent data sets, the skeleton and the distance of the boundary from the skeleton. The major benefit of this approach is that it allows a more flexible trade-off between accuracy of the approximation and bit-allocation cost, and thus, provides the possibility of better performance in the operational rate...
متن کاملFast Distortion Measurement Using Chord-Length Parameterisation within the Vertex-Based Rate-Distortion Optimal Shape Coding Framework
Existing vertex-based operational rate-distortion (ORD) optimal shape coding algorithms can use a number of different distortion measurement techniques, including the shortest absolute distance (SAD), the distortion band (DB), the tolerance band (TB), and the accurate distortion measurement technique for shape coding (ADMSC). From a computational time perspective, an -point contour requires ( )...
متن کاملA Fast Distortion Measurement Using Chord-Length Parameterisation within the Vertex- Based Operational Rate-Distortion Optimal Shape Coding Framework
Existing vertex-based operational rate-distortion (ORD) optimal shape coding algorithms use the shortest absolute distance (SAD) or alternatively either the distortion band (DB) or tolerance band (TB) as their distortion measuring technique. Each approach however can lead to inaccurate distortion measurements, though these can be avoided by employing the accurate distortion measurement techniqu...
