Digital image processing heavily relies on the connectivity of pixels, as it is a vital component for accurate object identification and analysis within an image. Grouping together pixels with similar features such colour intensity, allows formation meaningful patterns or objects, which essential recognition segmentation. This approach particularly valuable in photogrammetric imaging, video sur...

In this report the design, fabrication, and testing of inkjet-printed electrochromic pixels (ECPs) incorporating biochrome, xanthommatin (Xa) as programmable display units is described. As a redox sensitive chromophore, Xa present in some species physiological indicator with red (reduced) or yellow (oxidized) colors associated different behavioral developmental stages. These features have been ...

This project extends on the work done Drs. Anderson and Gaborski’ in Optical Character Recognition (OCR) of handwritten digits done back in the 1990s. Their work involved using the polynomial discriminant method, iterative training, and genetic algorithms to optimize the feature selection. This project involves several variations in technique over previous work. The first is the use of the matr...

In this paper, a new iris localization method for mobile devices is presented. Our system uses both intensity and saturation threshold on the captured eye images to determine iris boundary and sclera area, respectively. Estimated iris boundary pixels which have been placed outside the sclera will be removed. The remaining pixels are mainly the boundary of iris inside the sclera. Then, circular ...

endocrine hypothesis. For example, there must be in the population many men who have regularly donated blood every six months for many years. Obviously this is not equivalent to a monthly menstrual bleed. Nevertheless it would be interesting to see whether these men are in any way protected against coronary thrombosis as compared with a group of non-donors. (2) If true the concept would mean th...
