  • Writer Identification in Modern and Historical Documents via Binary Pixel Patterns, Kolmogorov–Smirnov Test and Fisher's Method

    سند علمی۲۰۱۶Arie Shaus, Eli Turkel

    The authors present a new method of writer identification, employing the full power of multiple experiments, which yields a statistically significant result. Each individual binarized and segmented character is represented as a histogram of 512 binary pixel patterns—3 × 3 black a

  • Comprehensive Colour Image Normalization

    سند علمی۱۹۹۸ECCVGraham D. Finlayson, Bernt Schiele, James L. Crowley

    The same scene viewed under two diierent illuminants induces two diierent colour images. If the two illuminants are the same colour but are placed at diierent positions then corresponding rgb pixels are related by simple scale factors. In contrast if the lighting geometry is held

  • Incorporating local image structure in normalized cut based graph partitioning for grouping of pixels

    سند علمی۲۰۱۳Inf. Sci.Debashis Sen, Niloy Gupta, Sankar K. Pal

    Keywords: Perceptual grouping Early human vision Image pixel grouping Local image structure Graph partitioning Normalized cut a b s t r a c t Graph partitioning for grouping of image pixels has been explored a lot, with normalized cut based graph partitioning being one of the pop

  • Normalization of multicolor fluorescence in situ hybridization (M-FISH) images for improving color karyotyping.

    سند علمی۲۰۰۵Cytometry. Part A : the journal of the International Society for Analytical CytologyYu-Ping Wang, Kenneth R Castleman

    BACKGROUND Multiplex or multicolor fluorescence in situ hybridization (M-FISH) is a recently developed cytogenetic technique for cancer diagnosis and research on genetic disorders. By simultaneously viewing the multiply labeled specimens in different color channels, M-FISH facili

  • Peripapillary retinal blood flow in normal tension glaucoma

    سند علمی۱۹۹۹Hak Sung Chung, Alon Harris, Larry Kagemann, Bruce Martin

    Aims—To determine if normal tension glaucoma (NTG) patients diVer from age matched controls in blood flow to the peripapillary retina, as measured with confocal scanning laser Doppler flowmetry (cSLDF; “Heidelberg retinal flowmetry”). Methods—12 NTG patients and 12 age matched co

  • PixelNet: Representation of the pixels, by the pixels, and for the pixels

    سند علمی۲۰۱۷CoRRAayush Bansal, Xinlei Chen, Bryan C. Russell, Abhinav Gupta

    We explore design principles for general pixel-level prediction problems, from low-level edge detection to midlevel surface normal estimation to high-level semantic segmentation. Convolutional predictors, such as the fullyconvolutional network (FCN), have achieved remarkable succ

  • Motion Segmentation and Tracking Using Normalized Cuts

    سند علمی۱۹۹۸ICCVJianbo Shi, Jitendra Malik

    We propose a motion segmentation algorithm that aims to break a scene into its most prominent moving groups. Instead of identifying point correspondences between the image frames, the idea to nd what groups of pixels are transformed from one image frame to another. To do this, we

  • Combination Photometric Stereo Using Compactness of Albedo and Surface Normal in the Presence of Shadows and Specular Reflection

    سند علمی۲۰۱۵CAIPNaoto Ienaga, Hideo Saito, Kouichi Tezuka, Yasumasa Iwamura

    We present a novel combination photometric stereo which can estimate surface normals precisely even for images including shadows and specular reflection. We can use photometric stereo if there are more than three input images. Therefore we can employ photometric stereo with nC3 c

  • Texture as a pixel feature for video object segmentation

    سند علمی۲۰۰۸Rakib Ahmed, Gour C. Karmakar, Laurence S. Dooley

    As texture represents one of the key perceptual attributes of any object, integrating textural information into existing video object segmentation frameworks affords the potential to achieve semantically improved performance. While object segmentation is fundamentally pixel-based

  • Optical Performances of Lensless Sub- 2micron Pixel for Application in Image Sensors

    سند علمی۲۰۱۱Weng Cho Chew, R. Marinelli

    In this paper we will report on the optical performances of submicron planar lensless pixels arranged in the 2 × 2 Bayer cell configuration, the basic element of CMOS colour image sensors. The 2D microlens array placed in front of each pixel in commercial devices has been replace
