RGB

El modelo RGB (Red, Green, Blue) se basa en la síntesis aditiva para producir diferentes colores mediante la suma de colores primarios. En el espacio CMYK-CMY (Cian, Magenta, Yellow, Key) trabaja con la síntesis sustractiva de sus colores primarios y un key que representa el color negro pues la combinación de los tres primarios no garantiza el color negro a pesar de sus propiedades de absorción. Otros espacios como el YIQ (Iluminance, In-phase, Quadrature) que se basa en el RGB y se aplicaba en

conocidos en la mezcla RGB se encuentran separados uniformemente, y el color contrapuesto a ellos son los (cian, magenta y amarillo) respectivamente CMY, y en el intermedio de cada color RGB con el CMY forman otro color, para un total de 12 colores que conforman éste círculo cromático. Estos colores mencionados anteriormente y más conocido como RGB, son los “colores primarios aditivos” y los colores CMYK forman los “colores primarios sustractivos”. Los colores primarios del RGB producen todos los

EL COLOR “La visión del color es una percepción. Sin la mente no existiría el color” Isaac Newton. El color es una propiedad de los cuerpos que depende de la luz del entorno y de su intensidad; todo lo que percibimos sobre el color en los distintos objetos que nos rodean es en realidad una sensación creada por nuestra mente con la ayuda de la luz que se refleja sobre los cuerpos y llega hasta nuestros ojos. La luz del entorno (luz solar) esta compuesta por varios colores, Isaac Newton

Each version of Photoshop since P7 has offered a brush engine, allowing you greater control over your painted effects. It was heralded as a breakthrough when it was created, and since then it 's only become better with age in each successive update. To learn how to use the brush engine to its fullest capacity, let 's look at how a custom brush can make something as simple as a coin come to life before your eyes (and not in that creepy, muppet sort of way.) (Disclaimer: I 've had people ask me complex

The gesture Gesture is the natural, nonverbal way that human can use to communicate with each other, and recently interface with computers and devices in order to have control upon them besides conventional input devices such as keyboard, mouse, and joystick. In general, gestures can be categorized into static and dynamic. • A static gesture refers to the position and poses of hand without any movement, which can be represented by a single image. • A dynamic gesture describes the hand movement

Communication is the art of transmitting ideas, thoughts ad knowledge from one person to another. Communication need not essentially mean verbal communication. Communication can be verbal and non-verbal. Non-Verbal Communication is the practiced means of interaction amongst the audibly challenged community. This audibly challenged community uses a region or country specific sign language to communicate their ideas and wants. Sign Language Translators are essential to bridge the communication gap

Agricultural production has increased manifold due to the advent of automation and intelligence in various stages of a crop’s life cycle. Introduction of such processes has led to a significant increase in the output and reduction in the costs incurred in manual labour and other farm equipment. A scheme where machine vision is implemented can be used to perceive the position of a fruit for harvesting. This technology has been used to develop both land and aerial based systems for fruit detection

performance watermarking by exploiting perceptual masking in DCT domain. The audio signal is partitioned into non-overlapping frames of length 4160. [41], D. Vaishnavi, et.al introduces two methods for invisible and robust watermarking proposed in RGB color space. In the first strategies, grey scale watermark is embedded at the blue coloration channel and in 2nd technique, blue colour watermark is embedded at the blue colour channel factors and then SVD applied on the blue channel of HI to retrieve

processing phases are used: image acquisition, enhancement, and segmentation, feature extraction and classification. Images were captured using a high resolution color camera and auto focus illumination light. Firstly they transformed the defected RGB image to the HSI color space then analyzed the histogram intensity channel then increased the contrast of the image. Fuzzy C Means (FCM) segmentation is used in this
