In recent years, digital cameras have become very popular. We use them every day and everywhere for "record"ing images of the real world. What I am going to talk about, however, is not how to record images but how to process recorded images.
CV (Computer Vision) technology is concerned with artificial systems which obtain information from images filmed by cameras. While a photo is often compared to an image projected to the retina, a CV can be thought of as a perceived image in the human brain.
These days artificial perception technology is used in various fields such as OCR (Optical Character Recognition), face recognition, human detection from a surveillance system and so on. Artificial perception may sound difficult but actually it is made possible by connecting CCTVs to a computer with CV technology. In today's society, therefore, all our activities may be perceived without being noticed.
However, most of the CV technologies are different from the mechanisms of information processing in the human brain. For example, easy problems for the human brain such as human detection from images are difficult for the computer and vice versa: barcode reading is an easy task for the computer while it is difficult for the human brain.
In this seminar, we will take an overview of CV technologies and their applications including -how can computers perceive the real world? -Some "eye"deas for applications and products when PCs have the "eyes".
