  • Fast L1-eigenfaces for robust face recogntion

    Publication Year: 2014, Page(s):1 - 5
    Request permission for reuse | Click to expandAbstract | PDF file iconPDF (420 KB)

    Face recognition using eigenfaces is a popular technique based on principal component analysis (PCA). However, its performance suffers from the presence of outliers due to occlusions and noise often encountered in unconstrained settings. We address this problem by utilizing L1-eigenfaces for robust face recognition. We introduce an effective approach for L1-eigenfaces based o... View full abstract»

  • Normalized cutswith soft must-link constraints for image segmentation and clustering

    Publication Year: 2014, Page(s):6 - 10
    Request permission for reuse | Click to expandAbstract | PDF file iconPDF (341 KB)

    Segmentation and clustering are common pre-processing tasks in many image understanding and computer vision applications. In some of these applications, expert users can often provide knowledge about which pixels or regions in an image should be grouped together, guiding the clustering or segmentation process to yield more meaningful results than could be achieved by fully automatic algorithms. In... View full abstract»

    Pseudo-color images are widely used on World-Wide-Web (WWW) to reduce file storage, RAM, video memory buffer space, and to speed up data transfers. A pseudo-color image consists of indices and indices are stored in a file with raster scan order. The investigations on different scanning patterns in filing of indices showed that further improvements on compression are possible. In this paper, we pro... View full abstract»

    Understanding the total mass balance of Earth's polar cryosphere is a significant aspect of estimating sea level rise due to climate change. Measuring ice sheet elevation and ground height is essential for determining the total glacier mass balance. Satellite-based and airborne photon-counting lidar sensors, such as the upcoming Ice, Cloud and land Elevation Satellite 2 (ICESat-2), will provide ac... View full abstract»

    Simulated remote sensing imagery can be very valuable for instrument design studies, analysis algorithm development and validation, and in verification of real image phenomenology. However, the question of simulation model validity and verification is important. This paper contributes to this topic by presenting a comprehensive comparison methodology between real and simulated hyperspectral imager... View full abstract»

    Minimally invasive surgery leads to significantly reduced morbidity and faster recovery times for patients. These advantages come at the cost of limited visual information available to the surgeon. Owing to the lack of direct visual feedback, visualization environments that enable three dimensional viewing and manipulation of medical images have become key, indispensable technology for minimally i...

    The speedup of color image processing algorithms remains of high interest as image resolutions continue to increase. Due to the intrinsic massive data parallelism, the techniques employed use multi-core processor systems or custom hardware. In the former the task is split in multiple threads at the software level, allowing as many data sets to be processed, as there are threads available. In the l... View full abstract»

    The analysis of remotely sensed spectral imagery has a variety of applications in both the public and private sectors, including tracking urban development, monitoring the spread of diseased crops, and mapping environmental disasters. The high spatial and spectral resolutions in hyperspectral imagery (HSI) make it particularly desirable for these types of analyses, as HSI sensors capture “color” i... View full abstract»

    The effectively large mirror size in a space telescope may be achieved by swarms of mirrors. In this paper, we present an analysis of such a space telescope, where a swarm of randomized micro-mirrors are combined to achieve the resolution comparable to a primary mirror equivalent to the entire distribution. The recorded speckle patterns, which vary randomly in time, are transformed into a high res... View full abstract»

    Ultrasound Shearwave Elasticity Imaging (SWEI) is a set of methods for measuring the elastic properties of biological tissues. Since the elastic properties of tissue are known to change with disease state, the application of these methods to clinical staging of disease is an active area of research. However, the fundamental signal generation and processing techniques required to make these elastic... View full abstract»

    We consider the use of graph cuts technique to efficiently segment the full tissue volume of the entire heart or important parts of it such as ventricles in Magnetic Resonance Imaging (MRI) scans for different species. With the segmented 3-D volume of the heart, simulations of electrical waves propagating through the tissue can be done. The modeled wave results can then be compared directly to the...
