    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (39 KB)

    Summary form only given. The early days of the Cold War had vivid memories of World War II and a challenge to see into denied territories. From this emerged a new capability to image from space-a capability that was innovative, daring, and one of the nation's most closely guarded secrets. This capability saw the development and operation in the 1960s of Corona-a series of photoreconnaissance satel... View full abstract»

    Remote sensing imaging systems map object points, located at 3D coordinates (x, y, z) in object space, to image points located at 2D (line, sample) coordinates in image space. For central projection imaging systems such as conventional cameras, the object-to-image mapping may be modeled as ratios of linear polynomials: line coordinate is P(x, y, z)/R(x, y, z) and sample coordinate is Q(x,y,z)/R(x,...

    We outline a novel approach for near real-time video registration based on sensor model parameter adjustments and the application of a Kalman filter. The goal of our precision video registration (PVR) development is to register video with a reference image to provide accurate 3D geolocations. Our sensor-based 3D treatment is unique since most registration approaches employ only simple image-to-ima... View full abstract»

  • Gradient-oriented profiles for unsupervised boundary classification

    Publication Year: 2000, Page(s):206 - 212
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (448 KB)

    We present a method for unsupervised boundary classification by producing and analyzing intensity profiles. Each profile is created by sampling an ellipsoidal neighborhood of voxels oriented along the image gradient. The profile is analyzed via nonlinear optimization to find the best fitting cumulative Gaussian. The parameters of the cumulative Gaussian parameterize the boundary directly yielding:...

    Water and ice clouds and other aerosols will significantly impact the performance of air and space based hyperspectral remote sensing systems. The effects are seen both in terms of optically thin layers intervening in the sensor line-of-sight and in the impact of cloud shadowed illumination on observed materials. While contamination is expected more often than not, many experiments and algorithms ... View full abstract»

    A fundamental problem in image analysis is the integration of information across scale to detect and classify objects. We have developed, within a machine learning framework, two classes of multiresolution models for integrating scale information for object detection and classification-a discriminative model called the hierarchical pyramid neural network and a generative model called a hierarchica...

    Tomographic reflection is a method that may be used to merge the visual outer surface of a patient with a simultaneous ultrasound scan of the patient's interior. The technique combines a flat-panel monitor with a half-silvered mirror such that the image on the monitor is reflected precisely at the proper location within the patient. In this way, the ultrasound image is superimposed in real time on... View full abstract»

    The advance of technology makes video acquisition devices better and less costly, thereby increasing the number of applications that can effectively utilize digital video. Compared to still images, video sequences provide more information about how objects and scenarios change over time. However, video needs more space for storage and wider bandwidth for transmission. Hence is raised the topic of ... View full abstract»

    Ultrasound is an attractive diagnostic medical imaging modality because of its safety, speed, relative low cost, and versatility. It is used successfully in imaging of shape, structure, and size in two and three dimensions; in the measurement of blood flow, and in quantitative characterization of tissue. The paper examines some of the models and processing techniques that make those applications p... View full abstract»

    The proposed system for image retrieval using multidimensional features (IRMF) characterises and matches image content in a high dimensional feature space of colour, texture and shape dimensions. By including the entire pyramid of low-, medium-, and high-level primitives, the semantics of image content at different feature levels can be represented and extracted efficiently for image retrieval.

    Much attention is now being focused on techniques to improve the quality and information content of ultrasonic images of the body. Many of these techniques employ digital pre-processing of coherent echo signals prior to image generation. Examples of these procedures include: resolution enhancement; contrast enhancement (using frequency-domain techniques) to suppress speckle; and imaging of spectra... View full abstract»

    We present a robust color quantization method based on the matrix of local pallets. The method proposed extracts a set of one-dimensional colors resulting from image partitioning. Image windowing depends upon the image variance which gives information on color dispersion. The color sets are then used to form the rows of the local pallet matrix that will be used as a smaller image. The selection of... View full abstract»

    Increasing the available imaging time of a remote sensing satellite over a specified ground area can be accomplished by placing the satellite in a higher, more elliptical orbit. This, however, will also require the satellite to be farther away from the Earth, thus reducing the resolution of the images. If the aperture size of the optics can be increased proportional to the increase in the satellit... View full abstract»
