Method for encoding a contour of an object in a video signal by using a contour motion estimation technique

Patent Number: 5,635,986

Patent Information

Abstract
A method for encoding a contour of an object predicts a current contour by using a current and a reconstructed previous contours and generates the motion vector representing a displacement between the reconstructed previous and the predicted current contours. A matched contour between the predicted current and the current contours is subtracted from the current contour to provide a differential contour. Thereafter, vertex points is determined based on a polygonal approximation for the differential contour. A set of approximation errors calculated at a predetermined number of sample points on each line segment between two vertex points is transformed and quantized to obtain a set of quantized discrete sine transform coefficients. The quantized discrete sine transform coefficients are encoded together with the motion vector, and the vertex points are encoded based on the predicted current contour for transmission thereof. And, the coded vertex information is decoded based on the predicted current contour, and the quantized discrete sine transform coefficients are converted into the reconstructed errors to reconstruct the differential contour. The reconstructed differential contour is added to the matched contour to provide the reconstructed previous contour.

PatentStat Scores in Not categorized
These scores show the percentile ranks for each metric.
For example, a score of 90 means that 90% of similar patents had lower scores.

Patent Grant Time

This patent had ► Log In grant time compared to others in this category.

Patent grant time can be influenced by many factors. Activities within the USPTO that are beyond the control of patent attornies can influence grant time, but short grant times can also indicate well-written patents and dedicated efforts to respond rapidly to USPTO office actions with strong arguments. Shorter grant times are preferable, and the scores for this section are inverse measures — higher scores are better.

Patent Claims

This patent has ► Log In claims compared to others in this category.

The number of claims in a patent is correlated with its strength. Because greater claim counts increase the cost of a patent, more claims can indicate the importance an applicant assigns to a patent. Importantly, some may elect to file claims across multiple patents. A higher score in this metric indicates more claims, relative to others in this category.

Citations From Other Patents

This patent has received ► Log In citations from other patents, than others in this category.

Citations from other patents are an important measure of the significance of a patent. More citations indicate that other technologies build on a patent. Higher scores in this metric are better, and indicate more citations from other patents.

Citations to Other Patents

This patent referenced ► Log In citations to other patents, than others in this category.

A lower number of citations to other patents can be a sign of diminished patent strength. More citations indicate dependence on more other technologies. Higher scores in this category are better, and indicate fewer citations to other patents.

Research and Innovation Indicators
These are percentile ranks — they indicate the percentage of peers with lower scores.

0%

Proximity to Basic Research

This patent has ► Log In proximity to basic research compared to others in this category.

Proximity to basic research is measured by comparing the number of citations to non-patent literature among a cohort of patents. Because most non-patent citations are primary research papers, a higher count indicates greater proximity to basic research.
