1. 21. Custom Lossless Compression and High-Quality Lossy Compression of White Blood Cell Microscopy Images for Display and Machine Learning Applications

   University essay from Lunds universitet/Matematik LTH

   Author : Terese Nilsson; Daniel Hamngren; [2013]
   Keywords : image compression; compression of medical images; blood cell microscopy; pca; regression analysis; discrete wavelet transform; reversible integer transform; lossy; lossless; lossy compression; lossless compression; Huffman; Huffman coding; image analysis; image processing; CFA; color filter array; bayer filter; Technology and Engineering; Mathematics and Statistics;

   Abstract : This master's thesis investigates both custom lossless compression and high-quality lossy compression of microscopy images of white blood cells produced by CellaVision's blood analysis systems. A number of different compression strategies have been developed and evaluated, all of which are taking advantage of the specific color filter array used in the sensor in the cameras in the analysis systems.

4. 23. Independent Domain of Symmetric Encryption using Least SignificantBit : Computer Vision, Steganography and Cryptography Techniques

   University essay from Högskolan Dalarna/Datateknik

   Author : Bhupathi Rajan Guruswamy Aarumugam; [2011]
   Keywords : Image watermarking; LSB; Vigenere Square; AI Techniques; Computer Vision; Steganography and Cryptography;

   Abstract : The rapid development of data transfer through internet made it easier to send the data accurate and faster to the destination. There are many transmission media to transfer the data to destination like e-mails; at the same time it is may be easier to modify and misuse the valuable information through hacking. READ MORE

5. 24. On Image Compression using Curve Fitting

   University essay from Blekinge Tekniska Högskola/Sektionen för datavetenskap och kommunikation

   Author : Amar Majeed Butt; Rana Asif Sattar; [2010]
   Keywords : Image compression; Multiplication limited and division free; Surface fitting;

   Abstract : Context: Uncompressed Images contain redundancy of image data which can be reduced by image compression in order to store or transmit image data in an economic way. There are many techniques being used for this purpose but the rapid growth in digital media requires more research to make more efficient use of resources. READ MORE

6. 25. Evaluating and Implementing JPEG XR Optimized for Video Surveillance

   University essay from Datorteknik

   Author : Lang Yu; [2010]
   Keywords : Video Surveillance; JPEG XR; Encoder; SoC; Evaluation; PSNR; Compression Ratio; Implementation; PCT; Quantization; Adaptive Prediction; Adaptive Entropy Coding;

   Abstract : This report describes both evaluation and implementation of the new coming image compression standard JPEG XR. The intention is to determine if JPEG XR is an appropriate standard for IP based video surveillance purposes. Video surveillance, especially IP based video surveillance, currently has an increasing role in the security market. READ MORE
