Concurrency and Computation: Practice and Experience, 2008
AbstractThe rapid development of space and computer technologies allows for the possibility to store huge amounts of remotely sensed image data, collected using airborne and satellite instruments. In particular, NASA is continuously gathering high‐dimensional image data with Earth observing hyperspectral sensors such as the Jet Propulsion Laboratory's ...

Orthogonal Bases Approach for the Decomposition of Mixed Pixels in Hyperspectral Imagery
IEEE Geoscience and Remote Sensing Letters, 2009The N-FINDR algorithm has been widely used in hyperspectral image analysis for endmember extraction due to its simplicity and effectiveness. However, there are several disadvantages of implementing the N-FINDR. This letter proposes an algorithm for decomposition of mixed pixels. It improves the N-FINDR in several aspects.

Stereo reconstruction with mixed pixels using adaptive over-segmentation
2008 IEEE Conference on Computer Vision and Pattern Recognition, 2008We present an over-segmentation based, dense stereo algorithm that jointly estimates segmentation and depth. For mixed pixels on segment boundaries, the algorithm computes foreground opacity (alpha), as well as color and depth for the foreground and background.

Customizing time of flight modulation codes to resolve mixed pixels
ACM SIGGRAPH 2013 Posters, 2013We couple custom binary sequences with sparsity based approaches to address the multi-path problem in time of flight imaging. In particular, we utilize maximum length m-sequences that allow us to produce non band-limited correlation functions. Coupled with a tailored sparse deconvolution approach, we are able to resolve the constituent phases and ...

Consequences of Mixed Pixels on Temperature/Emissivity Separation
2007This report investigates the effect that a mixed pixel can have on temperature/emissivity seperation (i.e. temperature/emissivity estimation using long-wave infra-red data). Almost all temperature/emissivity estimation methods are based on a model that assumes both temperature and emissivity within the imaged pixel is homogeneous.

The use of Hough transform to mixed pixel classification
IEE Colloquium on Image Processing for Remote Sensing, 1996Burned forest regions have to be monitored for several years after the fire so that the regeneration processes can be evaluated. The authors assess the danger of desertification conditions ensuing in the site of a burned forest in the Mediterranean region.

A mixed-signal CMOS DTCNN chip for pixel-level snakes
2004 IEEE International Symposium on Circuits and Systems (IEEE Cat. No.04CH37512), 2004This paper introduces the processing core of a full-custom mixed-signal CMOS chip intended for pixel-level snakes. Among the different parameters to optimize on the top-down design flow our methodology is focused on area. This approach results in a single-instruction-multiple-data chip implemented by a DTCNN with a correspondence between pixel and ...

Pansharpening of Clustered MS and Pan Images Considering Mixed Pixels
IEEE Geoscience and Remote Sensing Letters, 2017The component substitution (CS) scheme is one of the most efficient models used by different image fusion algorithms when merging multispectral and panchromatic images, acquired with different spatial and spectral resolutions. In this letter, a new CS-based image fusion method is proposed to reduce color distortion.

Target signature-constrained mixed pixel classification for hyperspectral imagery
IEEE Transactions on Geoscience and Remote Sensing, 2002Linear spectral mixture analysis has been widely used for subpixel detection and mixed pixel classification. When it is implemented as constrained LSMA, the constraints are generally imposed on abundance fractions in the mixture. In this paper, we consider an alternative approach, which imposes constraints on target signature vectors rather than target

A Mixed Pixels Estimation Method for Landsat-7/ETM+ Images
2012In this paper, the estimation method of the mixed pixel for satellite images has been proposed. A mixed pixel consists of several categories and the aim of this study is to estimate the mixture ratios of the categories. The filter of neighborhood pixels had been proposed. In this paper, the optimal filter coefficients have been considered in detail.
