A hybrid (statistical/structural)approach is presented, for scale- and orientation-invariant recognition of multi-component cartographic symbols. A decision-tree classifier (DTC) ...
This paper presents an application of optic flow estimation to image metamorphosis. It uses a state of the art optical flow algorithm to do image metamorphosis, which is used in v...
We present a procedure to split (or segment) touching numerals. We are neither assuming a dominant orientation for the text direction nor long character strings. The basic idea is...
This paper presents an efficient extraction method of closed loops as primitive symbols of line drawings, and an robust line drawing understanding system incorporating this extrac...
The visual perceptional ability of computer systems to understand the environment is desirable in engineering design and manufacturing where automation is anticipated. I n order t...
