Stereo Image Measurement Using Geometrical Invariants

Stereo Correspondence Using Moment Invariants

Fragmentation measurement using image processing

In this research, first of all, the existing problems in fragmentation measurement are reviewed for the sake of its fast and reliable evaluation. Then, the available methods used for evaluation of blast results are mentioned. The produced errors especially in recognizing the rock fragments in computer-aided methods, and also, the importance of determination of their sizes in the image analysis ...

Restoration of a Distorted Image of Document Using Stereo Measurement

In this paper, we propose a method for correcting image distortions occurring when digitizing thick documents. The method corrects geometrical distortion using the document shape acquired by stereo measurement. Moreover, it obtains a fine restoration result by combining the better detailed portions in a stereo image pair. In an experiment, we show the validity of the method by investigating cha...

Analyzing Image Sequences using Invariants

Recent research in invariant theory has determined the fundamental geometric relation between objects and their corresponding images. This relationship can be used to extract 3-D models from image sequences. This capability is extremely useful for image sequence compression, understanding , indexing, interpolating, and other applications. This paper presents a high level example of how a 4-D mo...
