  1. 1. Compressive Sensing: Single Pixel SWIR Imaging of Natural Scenes

    Master-uppsats, Linköpings universitet/Datorseende

    Författare :Andreas Brorsson; [2018]
    Nyckelord :Compressed sensing; Compressive sensing; CS; Compressive imaging; compressed imaging; CI; SPC; Single pixel camera; single pixel imaging; SWIR; Short-wavelength infrared; IR; infrared; Natural Scenes; DMD; Digital micromirror device; FOI;

    Sammanfattning : Photos captured in the shortwave infrared (SWIR) spectrum are interesting in military applications because they are independent of what time of day the pic- ture is captured because the sun, moon, stars and night glow illuminate the earth with short-wave infrared radiation constantly. A major problem with today’s SWIR cameras is that they are very expensive to produce and hence not broadly available either within the military or to civilians. LÄS MER

  3. 2. Compressive Sensing in Medical Ultrasonography

    Uppsats för yrkesexamina på avancerad nivå, KTH/Ljud- och bildbehandling

    Författare :Julien Richy; [2012]
    Nyckelord :;

    Sammanfattning : The recently introduced compressive sensing (CS) theory allows – under certain assumptions – to recover a signal sampled below the Nyquist sampling limit. Compressive sensing can be applied for two purposes. First, to decrease the number of samples needed to capture the information, thus allowing faster acquisitions. LÄS MER

  4. 3. Compressed Sampling for High Frequency Receivers Applications

    Master-uppsats, Avdelningen för elektronik, matematik och naturvetenskap

    Författare :xiaofei bi; [2011]
    Nyckelord :Compressive Sampling CS ; sparse representation; measurement matrix; signal reconstruction.;

    Sammanfattning : In digital signal processing field, for recovering the signal without distortion, Shannon sampling theory must be fulfilled in the traditional signal sampling. However, in some practical applications, it is becoming an obstacle because of the dramatic increase of the costs due to increased volume of the storage and transmission as a function of frequency for sampling.
