Introduction In color reproduction, gamut or the color gamut is a certain complete subset of colors, which can be accurately represented in a given circumstance such as given color space [1]. In another words gamut literally means the total range of possibilities that can be accomplished from red, green and blue (RGB) for a particular device [2]. If certain color cannot be reproduced accurately there is a way how to calculate the color difference by adequately describing the color by numerical…

Every day, an image saves someone’s life. How? A diagnostic image can provide doctors with knowledge about a patient’s health. Images are an innovation that has changed the way people live, not only in the health industry but in their personal life, too. They allow people to capture memories and share their experiences with others. Digital and diagnostic are two types of images; diagnostic images are used by doctors while digital images are used by most people. The two types of images are…

Nature reclaims technology through artificial intelligence of Virtual Reality headset wearables. This assignment will give, in detail, whether nature and technology are positioned as binary or opposites. Furthermore, a design or artwork of a form of interactive technology will be included, to constitute the relationship between human user and that interactive technology. Also the assignment will be focusing in depth towards the meaning or definitions for the words ‘technological’, ‘nature’ and…

Increased graphics, better hardware and software, faster connections and tracking systems are only the tip of the iceberg. A major add-on to current VR technology in the future will be the improved headsets. Currently, headsets are thick and most of them requires straps…

Chapter 1 Introduction Digital photography is a form of photography that uses cameras containing arrays of electronic photodetectors to capture images focused by a lens, as opposed to an exposure on photographic film. Here images are captured and stored in file for further processing. Digital photography aims to produce an image that gives an illusion of a real environmental image. Inorder to produce an image that provides visual richness and sets the mood of the environment the important…

1. ABSTRACT The essence of an image is a projection from a 3D scene onto a 2D plane, during which the depth information is lost. The 3D point corresponding to a specific image point is constrained to be on the line of sight. From a single image, it is very difficult to determine the depth information of various object points in an image. If two or more 2D images are used, then the relative depth point of the image points can be calculated which can be further used to reconstruct the 3D image by…

compress the light and have it appear on the final processed photo or computer in the same manner the eyes sees it. According to Photography.TutPlus, a good digital camera can capture a dynamic range in the ratio of 1,000:1, unlike the human eye, which can see a scene with 10,000:1. This means the human eye is much more capable of capturing wide variety of brightness compared to the camera. Depending on your preference, a computer editing software such as Photoshop, Lightroom and Photomatix Pro…

By representing the 2D point (x,y) by a 3D point (x,y,z) using the homogenous coordinates, the perspective projection can be represented as: [█(x`@y`@z`)] = [█(f 0 0 0@0 f 0 0@0 0 1 0)] [█(X@Y@Z@1)] ……………………………....…

This step completes the segmentation removing static objects from the grayscale images $T_i$ using Eigen-Background decomposition. First, each image $T_i \in \mathbb{R}^{n_x\times n_y} $ is reshaped into a column vector $I_i \in \mathbb{R}^{n_p\times 1}$. These $n_t$ vectors become the $i-th$ column of a video matrix $A(n_p\, , \, n_t)$, after having removed the average image: \begin{equation} A_{(n_s \times n_t)}=\begin{pmatrix} \hat{I}_1 & \hat{I}_2 & \cdots & \hat{I}_{n_t}…

The type of scanner is a modality-dependent feature. For example, MRIs and CT scanners are differ in size and functions. In medical ultrasounds, patients are not required to enter a scanner to be tested for CAD. These intrinsic modality-dependent differences were therefore considered as important test-specific attributes. In a DCE on scanning modalities to diagnose focal liver lesions, the type of scanner used was studied and shown to influence patient preferences for diagnostic tests (Whitty et…
