3. 12. Visual Quality Improvement of Digital Video by Stabilization Using Adaptive CMAC Filtering

   Master-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

   Författare :Amir Zahoor; Wittaya Koodtalang; [2013]
   Nyckelord :Digital video stabilization; DVS; Cerebellar model articulation controller; CMAC; Smoothness index; Peak signal to noise ratio; Point spread function;

   Sammanfattning : A Digital Video Stabilization (DVS) system removes the unwanted shaking in the videos acquired by hand-held cameras and preserves the panning. In this thesis work, a digital video stabilization model is proposed based upon adaptive cerebellar model articulation controller (CMAC) filtering. LÄS MER

4. 13. 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.
