“…Returning again to the first image we follow a reg i on edge to the ri ght through the data structure as in (20). At the next end of the edge , we once again appl y the feature extraction and corre llation check.…”

Studies in Image Analysis: Using encoded Stereo Images for Scene Analysis.

“…Of the methods U investigated , the technique of run length coding was found to be the most promising . A method of coding was developed , as outlined in [ 4 ] , whic h is quit e amenable to hardware implenientation and whic h results in a data storage area reduction which , at wors t , is 1:1 but may yield 4:1 to 8:1 reductions with little degradat ion in the image quality necessary for analysis . It should be noted here that this reduction i~ in storage area words , not in bit s as commonly used for transmission purposes and that full spat ial and intensity resolution is maintained .…”

“…A relat Ively straight forward approach to depth determination for the case of planar polygonal objects is outlined . This approach uses the encoded data structure described above along with the operations described in [ 4].…”
