Method for identifying view order of image frames of stereo image pair according to image characteristics and related machine readable medium thereof

摘要

A method for identifying an actual view order of image frames of a stereo image pair includes at least the following steps: receiving the image frames; obtaining image characteristics by analyzing the image frames according to an assumed view order; and identifying the actual view order by checking the image characteristics. In addition, a machine readable medium storing a program code is provided. The program causes a processor to perform at least the following steps for identifying an actual view order of image frames of a stereo image pair when executed by the processor: receiving the image frames; obtaining image characteristics by analyzing the image frames according to an assumed view order; and identifying the actual view order by checking the image characteristics.

1. A method for identifying an actual view order of image frames of a stereo image pair, comprising:
receiving the image frames; obtaining image characteristics by analyzing the image frames according to an assumed view order, wherein the step of obtaining the image characteristics comprises:
selecting a plurality of feature point correspondence pairs from the image frames; andcomputing parallax values of the feature point correspondence pairs to generate the image characteristics; and identifying the actual view order by checking the image characteristics, wherein
the step of identifying the actual view order comprises:referring to the parallax values to count positive parallax values, negative parallax values and zero parallax values and respectively obtaining a first representative value, a second representative value and a third representative value; andverifying the assumed view order to determine the actual view order according to the first representative value, the second representative value and the third representative value.
