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

    Master-uppsats, Lunds universitet/Matematik LTH

    Författare :Terese Nilsson; Daniel Hamngren; [2013]
    Nyckelord :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;

    Sammanfattning : 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.

  5. 29. Video Encryption

    Kandidat-uppsats, Institutionen för datavetenskap, fysik och matematik, DFM

    Författare :Fatih Levent Yilmaz; [2011]
    Nyckelord :video encryption; encryption; mpeg; jpeg; line cut and rotate; video scrambling;

    Sammanfattning : Video Encryption is nearly the best method for blocking unwanted seizures and viewing of any transmitted video or information. There are several useful techniques that are available for encryping videos. LÄS MER

  7. 30. On Image Compression using Curve Fitting

    Master-uppsats, Blekinge Tekniska Högskola/Sektionen för datavetenskap och kommunikation

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

    Sammanfattning : 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. LÄS MER
