Unsupervised object-based spectral unmixing for subpixel mapping [PDF]
Subpixel mapping (SPM) addresses the widespread mixed pixel problem in remote sensing images by predicting the spatial distribution of land cover within mixed pixels. However, conventional pixel-based spectral unmixing, a key pre-processing step for SPM,

A and B: A 1st level analysis of a control subject and a symptomatic PCS patient.
, 2014 The CO2 response was assessed at the p = 0.001 level in both. The number of voxels responding to CO2 in the control patient (C-013) was 94% of the total brain voxel count at this level of statistical significance. In the symptomatic PCS patient (mTBI-004)

Online correction of scanning probe microscopes with pixel accuracy [PDF]
, 2000 In this project ''Online Control of Scanning Probe Microscopes with Pixel Accuracy'', the development of an algorithm is described that enhances the measurement uncertainty of software controlled SPM by one order of magnitude from 2% to 0.2 %. The SPM is

Hard-Constrained Hopfield Neural Network for Subpixel Mapping [PDF]
Subpixel mapping (SPM) can address the mixed pixel problem by producing land cover maps at a finer spatial resolution than the input images. The Hopfield neural network (HNN) method has shown great advantages in SPM and various extended versions have ...
