JPEG 2000

Department of ECE, P. A. College of Engineering and Technology, Pollachi. 1 karthikasprof@gmail.com 2 jaikumarkarthi@gmail.com Abstract -- The JPEG 2000 image compression standard is designed for a broad range of data compression applications. The Discrete Wavelet Transformation (DWT) is central to the signal analysis and is important in JPEG 2000 and is quite susceptible to computer-induced errors. However, advancements in Field Programmable Gate Arrays (FPGAs) provide a new vital option for

Medical imaging, as we all know, is the process of taking images of various parts of the human body for diagnostic and surgical purposes. Some of the popular medical imaging modalities are X-ray radiography, Magnetic resonance imaging, Medical ultrasound, Computed tomography etc. Since, these images contain clinical data of extreme importance for treatment follow-ups and are acquired at cost of radiation exposure, infrastructure, money and time involved. Thus, once acquired, the medical imaging data

ABSTRACT We focus on approximate algorithms for the computation of the 8-point DCT. While not computing the DCT exactly, approximate methods can provide meaningful estimations at low-complexity requirements. Prominent techniques include the signed discrete cosine transform (SDCT), the Bouguezel–Ahmad–Swamy (BAS) series of algorithms, and the level-1 approximation by Lengwehasatit-Orteg. All above mentioned techniques possess extremely low arithmetic complexities. These techniques have some defaults

2. Export the image as a JPEG file: • Ensure a high quality image, with a score of 11 or more on Photoshop scale (or equivalent). • The shortest side of your picture (the width for a portrait, the height for a landscape) should have a resolution of at least 3,000px. • The size

A guide for Image Optimization for a website For every photographer, amateur and professional the only thing more important than your camera is your pictures. The same goes for designers, artists and generally every person who spend a significant amount of time and energy in creating beautiful and meaningful images and obviously you’d want to show off your creations to the world. Then comes uploading those on a website or social media to be shared generously amongst your clients, peers and friends

II. LTERATURE 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

Discrete Wavelet Transform DWT is a frequency based transform which is performed on wavelets. It can be 1-D, 2-D and etc. It divides an image into four sub-bands, namely  LL (Low resolution image)  HL (Horizontal)  LH (vertical)  HH (diagonal) This division can be performed up to many levels. It captures not only notion of frequency content but also temporal content. Wavelets provide a mathematical way of encoding information in such a way that it is layered according to level of detail

4.1.1 Introduction Everything is cross-platform now. That's part of the reality that we live in - a multifaceted, multimedia world - and I'm delighted to be a part of that. -Robert J. Sawyer After the advent of technology and computers, lot of things around the world have changed. The way people communicated has undergone a remarkable change thanks to automation and machines. Mobile technology is another field which has revolutionized communication, information sharing and data retrieval. The world

a final conclusion about the best ones to use for certain tasks. Seen as there are numerous different uses for images it means that the quality will differ for different purposes. The formats which I will be discussing within this report include JPEG, GIF’s, TIF, PSD and BMP. All these formats are made for different reasons and I will be explaining these differences in quality and file size. Each format varies in the depth of the colour within the image, some have larger colour depth meaning that
