Essays on Pixel

Errors involved in digital image capturing and processing can either be systematic or random. Systematic errors are classified into geometric distortions, spectral errors and distortions. Geometric distortions are caused by sensor-Earth geometric variations which affects the position of a pixel relative to other pixels,. In digital images, the pixel position is compared to the other pixels in the scene and the absolute position of the pixel relative to real coordinates in latitudes and longitudes. Geometric distortions can render the image and the information expected to be derived from the image as useless,. This is because the image is sometimes ...

Digital image analysis is a method of extraction of useful information from digital images by using various digital image processing techniques. A digital image is a two-dimensional matrix that consists of great number of smallest addressable elements – pixels. Each pixel has its own digital characteristics, such as address and color representation. Digital image characteristics have two main measures: spatial resolution that is focused on capturing details and tonal resolution that is used to measure color, dynamic range and bit-depth. Higher tonal, spatial, and color values mean larger sizes of digital image file. (Peterson, 2005, pp. 1-2) The appropriate method ...

Steganography is a scientific method of concealing confidential information or data in another set of data. Steganography can be used in conjunction with cryptography for the purpose of data protection. The methods applied in steganography use images, audio or video files for protecting the different types of data. Piracy of copyrighted materials and unsanctioned observation is avoided by using steganography. (Techopedia,2017) Steganography is extensively used for digital watermarking. A watermark is used for authentication of the source of a document. Images of graphic artists posted on web pages are digitally watermarked for proof of ownership. This is useful ...

I. Environment Scan: Strengths, Weaknesses, Opportunities & Threats Currently, Google is an Internet company which has gone well beyond search business (Edelman & Eisenmann, 2011). Against a stated philosophy of "It is best to do one thing really, really well," Google has diversified core business, i.e. search and paid listings, into a broad range of product and service offerings cutting across numerous industries and business activities. Notably, Google has diversified from search business into communication applications, productivity applications and computing operating systems (Edelman & Eisenmann). This expansion mandates an environment scan of Google's to be not only limited to search business but ...

Issues in Digital Photography

The essay summarizes and compares the arguments by two authors, Rachel Wells, and Carol Squlers on Digital images and photography in Digital age. The paper focuses on how the authors challenge traditional modes in image making while advocating their views. The chapter on “Digital Scale: enlargement and intelligibility in Thomas Ruff’s jpeg Series “inspects the use of pixelation in Thomas Ruff’s jpeg series1.Ruff looked into the disclosure of the pixel grid when enlarging digital images. He has long been interested in reproduction and manipulation of digital images. His jpeg series works on digital images found on the ...

Diet is necessary to everyone for continuing the life. Its utility occupies a significant position in the biological world. The unique benefit the diet provides is of paramount importance in achieving the health-specific goals. However, alongside with knowing about the diet and its role in health, it is essential to develop certain awareness about its assessment. With the advancement of technology various approaches were believed to exist with regard to the dietary assessment.
