IMAGE EVALUATION METHOD FOR ROTARY TILLAGE OPERATION QUALITY

Quality Evaluation Method for Underwater Image Communication

A simulation based on Gilbert-Elliot packet loss model is developed to simulate an image transmitting system in underwater acoustic channel. This developed system is applied as a platform to study the relation between image quality assessment parameter PSNR, image activity measure (IAM) and channel’s packet loss rate. A group of sample images were transmitted in this communication system and a ...

Tillage and soil quality Tillage practices for sustainable agriculture and environmental quality in different agroecosystems

For centuries tillage has been used to prepare suitable seedbed to grow crops, and to control weeds and incorporate fertilizers, pesticides, manures and other amendments. In early years conversion of native ecosystems by tillage helped to unlock nutrients stored in soil organic matter, and thus `mine' naturally fertile soils to grow crops with minimum inputs for the growing population. However,...

Image Quality Evaluation

Image quality evaluation plays an important role in the design of many Hewlett Packard products, including imaging peripherals such as digital cameras, scanners, printers and displays. This chapter describes some of the engineering tools my colleagues and I are developing at Hewlett Packard Laboratories to help us evaluate how our customers perceive the image quality of our products. The engine...

Image Quality Ranking Method for Microscopy

Automated analysis of microscope images is necessitated by the increased need for high-resolution follow up of events in time. Manually finding the right images to be analyzed, or eliminated from data analysis are common day-to-day problems in microscopy research today, and the constantly growing size of image datasets does not help the matter. We propose a simple method and a software tool for...
