Goals of Computer Vision • To make useful decisions based on sensed images • To construct 3D structure from 2D images.
Related Areas of Computer Vision • Computer Graphics • Image Processing • Pattern Recognition • Artificial Intelligence • Virtual Reality
Applications of Computer Vision • Human Face Identification • Image Database Query • Inspecting Products • Examining the Inside of a Human Head (MRI) • Optic Character Recognition (OCR) • Analyze Satellite Image • Unmanned Autonomous Vehicle (UAV)
How do we see an object? Light Eye Object • Luminance Lightness Rods • Chrominance Color Cones Human eye is more sensitive to luminance than to chrominance
Types of Images • Analog Image • Digital Image • Binary Image • Gray-scale Image • Color (Multispectral) Image
Image Formats • Vector Image • Bitmap Image • RAW no header • RLE (Run-Length Encoding) • PGM,PPM,PNM (Portable Gray Map) • GIF (Graphics Interchange Format) no more than 256 colors • TIF (Tag Image File Format) Scanner • EPS (Encapsulated Postscript) Printer • JPEG (Joint Photographic Experts Group) Compression ratio • MPEG (Motion Picture Experts Group) Video
