ENT363/4Machine Vision Systems(Core Course) Lecture 2 Introduction to Machine Vision From wikipedia: Machine vision (MV) is the technology and methods used to provide imaging-based automatic inspection and analysis for such applications as automatic inspection, process control, and robot guidance in industry. “The scope of MV is broad”.
WHY? • Interest in image processing stems from two principle application areas: • improvement / enhancement of pictorial information for human interpretation • do you have example in mind? • Processing of image data for storage, transmission, and representation for autonomous machine perception. • which is why we learn this course!
Some Definition • Image Images are two-dimensional projections of the three-dimensional world • Vision Vision is the most Complex of human senses, about a fourth of the brain’s volume is devoted to it. • Image Processing Processing images to give new images • Computer Vision Deals with what the images mean – aims to interpret images • Machine Vision Apply vision and image processing • Vision System A Vision System recovers useful information about a scene from its two dimensional projections
Fundamental steps & Components of Machine Vision Systems • Describe images, objects and physical world – dedicated camera and frame grabber are used. • Mathematical models of image and objects and knowledge representation. • Image sampling, quantization Image acquisition • Improves image for human and computer consumption, highlight / extract relevant feature • Remove noises, deblurred etc • Color Conversion • Segmentation and representations • Extract features such a edge, regions, surfaces etc. • Measurement Analysis - measure features on the object Image processing • Determine which is what in an image • Locate objects in the image, classify them and build 3D models. • Input signal for the next actions.
