Automatic Detection of optic disc location in Color Fundus Retinal Images Using Circle Operator Abstract—In this work a method is proposed to detect optic disk (OD) automatically in color retinal fundus image without using background mask and blood vessels. Based on the properties of OD, an idea of circle operator is presented here. This method has been applied on six public databases and the promising results are obtained. The experimental results indicate that this proposed method of automatic

Chapter 3. Image Detection 1. Introduction Using right algorithm, can make image sensor sense or detect practically anything. Image sensors are one of the important sensors been used in robotics industry because they are so flexible, but there are two drawbacks with these kind of sensors: 1)they output lots of data, dozens of megabytes per second, and 2) processing this amount of data can overwhelm many processors. And even if the processor can keep up with the data, much of its processing power

Introduction Part A In this Assignment, I create an advertisement in adobe Fireworks that is 1500x2100 and 300dpi .In this advertisement I use some raster and vector Images. There are Number of tools in adobe firework but, I use mainly Pen tool ,shape tool, paint bucket tool, eyedropper, vector path and Select tool. The Effective Tools In this Assignment, I worked on Adobe Firework which is a powerful software to create , posters, Vector creation. there another which is knows pencil tool which

In today’s revolution oriented environment, multimedia contents play a vital role in a wide range of applications, products and services. The high usage of these contents demand efficient searching and indexing for users. This demand has drawn substantial research attention towards image retrieval systems in the last few decades. Many great methods have been proposed, which offer numerous advantages like the following. (i) These techniques are fully automatic and avoid the manual errors of text-based

“Mixing colors gives birth to an infinite number of new colors, but there exist only four true colors – like four elements – from which one can make numerous other colors. Red is the color of flame, blue – the color of air, green – the color of water and the earth has grey and ashy”. Theorists who lived later including Leonardo da Vinci and Isaac Newton , proved that the three basic colors are in fact red, blue and yellow. Modern theory of color was worked out by an American artist Albert Henry

Skin color detection is considered one of the most popular techniques of segmentation and tracking because of its simplicity. The idea behind using this technique is that skin color is different from other object’s color and then can be used to identify human gesture part. There are several color spaces such as RGB, YIQ, YUV, and generic color model that are used to distinguish skin pixels from non-skin pixels through comparing a predefined skin color model (skin pixels) with pixels of the input

INTRODUCTION Aim: Throughout this laboratory we aimed to understand the processes used to achieve the development of image capture, display, colour processing and finally object tracking. In particular, we aim to learn the I2C protocols to program the registers used to configure the camera, how to convert a raw image to a full colour image, detect a selected colour and then track it. Block Diagrams and images for the image processing steps: The block diagram in Figure 1, illustrates the processing

Chapter 3 Technical Back Ground Controlling Mouse 1.1 Moving Mouse Cursor We utilized the forefinger as a cursor controller to control mouse cursor. We utilized two distinctive methodologies for moving the mouse cursor. The principal strategy is mapping cursor control. It implies that the pointer on a camera screen can position maps to a desktop screen position. At the end of the day, the mouse cursor is put on the desktop window alongside the forefinger tips position showed on the camera screen

object, or it could refract or totally transmitted through the object44, 45. The wavelengths (colors) that are reflected, refracted or transmitted are perceived by receptor cells (i.e. rods and cones) in the eye and recognized by the brain as a specific color. The wavelengths of visible light range from approximately 400 to 700 nm45, 46. The wavelengths that are transmitted, refracted or reflected create the color that is perceived and till about the translucency level of the material. If all light is

REVIEW 1)Homayoun Bagherinia, Roberto Manduchi,had proposed the for University of California, Santa Cruz”A novel approach for color barcode decoding using smartphones” The use of colors increases the information storage capacities in barcodes. Increasing the number of color stolen code information makes the decoding a challenging task due to the dependency of the surface color on the illuminant spectrum, viewing parameters, printing device and material. The decoding becomes more challenging if a mobile
