    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»

    Summary form only given. This paper reviews the early years of remote sensing of the earth's surface, as distinguished from its atmosphere, and shows the influence of manned space flight, in particular the Apollo Program. The first orbital-altitude pictures of the earth were taken from sounding rockets in the 1950s, and eventually led to terrain photography by astronauts of the Mercury, Gemini, an...

    Digital image compression is an important technique in digital image processing. To improve its performance, we attempt to speed up the design process and achieve the highest compression ratio where possible. For speed improvement, we used a fast Kohonen self-organizing neural network algorithm to achieve big saving in codebook construction time. For compression purpose, we propose a new approach,...

    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,...

    Cited by:  Papers (1)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (536 KB)

    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»

    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.

    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»

    We present a method to perform target detection in EO imagery by rapidly reducing imagery data volume as algorithmic complexity increases. The technique is based on perceptual grouping of segmented regions through generic geometric, intensity and topology constraints that distinguish vehicles from the background. At each of the three processing stages, greater than 90% data reduction can be achiev... View full abstract»

    A novel approach to automated road extraction using a hybrid combination of self-organization and model-based extraction techniques is introduced. We use a self-organized mapping technique to first delineate the medial axis topology of road features. This is accomplished through a local clustering of class-binarized spatial information provided from a region segmentation. Since the cluster analysi... View full abstract»

    A software tool has been developed to predict the SAR signatures created by buildings. The tool is an integration of a building model editor with a SAR signature simulation algorithm. The SAR signature simulator is capable of producing single and multiple bounce signatures from building model inputs.

    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:...

    We present an error-robust channel-optimized image coder for the transmission of imagery over noisy channels. The proposed coder uses a robust channel-optimized trellis-coded quantization (COTCQ) stage that is designed to optimized the image coding based on the channel characteristics. The resilience to channel errors is obtained only at the level of the source encoder, with no explicit use of cha... 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»

    Volume holographic memory can offer massively parallel associative search capability in addition to high capacity data storage. After holograms have been stored into a photosensitive material, an optical correlation of an input user query against all co-locationally stored patterns can be made simultaneously, resulting in fast search speed.

    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»

    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»

    A new vector coding for natural image, which has a compressive algorithm, is presented and the image features showed in this method are described. The pixel-value-boundary contours on RGB or YCrCb planes of natural images are expressed by function approximation and then their contour shapes are predicted from similar contours in the decoder side. The proposed vector coding method has two main meri... View full abstract»
