Human Visual System Lecture
Nowadays, digital images and video are everywhere. Image Processing revolutionizes very many domains, notably:
-Digital Media (video/image/movie) Content Production and Broadcasting, Social Media Analytics,
-Medical/Biological/Dental Imaging and Diagnosis,
-Big Visual Data Analytics,
-Internet and Communications (media broadcasting, streaming).
-Scientific Imaging of any sort, e.g., Remote Sensing, Environment Sensing.
Photoshop and many other image processing tools are ubiquitous.
Furthermore, Image Processing is typically the first step that enables diverse applications, in unison with Computer Vision and Machine Learning:
-Autonomous Systems (cars, drones, vessels) Perception,
-Robotics Perception and Control,
-Intelligent Human-Machine Interaction,
-Anthropocentric (human-centered)Computing,
-Smart Cities/Buildings and Assisted living.
This lecture overviews the Human Visual System that has many applications in understanding image perception and image quality issues. It covers the following topics in detail: Human Visual System (eyes and visual pathway, stereo vision). Retina (rods, cones, ganglion receptive fields, color theory). Visual Pathway (optic nerves, optic chiasma, optic tract, Lateral Geniculate Nucleus, Corpus Callosum, optic radiation). Visual Cortex: V1 (primary visual cortex) and V2-V6 visual areas. Visual defects, e.g., refractive errors, Color related visual defects, Form visual defects, Motion visual defects.
