An Adaptive Subpixel Mapping Method Based on MAP Model and Class Determination Strategy for Hyperspectral Remote Sensing Imagery

Posted on February 2, 2016 by Matlab-Projects |

The subpixel mapping technique can specify the spatial distribution of different categories at the subpixel scale by converting the abundance map into a higher resolution image, based on the assumption…

Remote Sensing Image Segmentation Based on an Improved 2-D Gradient Histogram and MMAD Model

Posted on February 2, 2016 by Matlab-Projects |

A novel remote sensing image segmentation algorithm based on an improved 2-D gradient histogram and minimum mean absolute deviation (MMAD) model is proposed in this letter. We extract the global features as a…

Adaptive artificial bee colony based parameter selection for subpixel mapping multiagent system in remote-sensing imagery

Posted on February 2, 2016 by Matlab-Projects |

Remote sensing has become an important source of land use/cover information at a range of spatial and temporal scales. The existence of mixed pixels is a major problem in remote-sensing image classification. Although the…

Toward Evaluating Multiscale Segmentations of High Spatial Resolution Remote Sensing Images

Posted on February 2, 2016 by Matlab-Projects |

Object-based analysis of high spatial resolution remote sensing images addresses the matter of multiscale segmentation. However, existing segmentation evaluation methods mainly focus on single-scale segmentation. In this paper, we examine the issue of supervised…

Low-Complexity Topological Derivative-Based Segmentation

Posted on February 2, 2016 by Matlab-Projects |

Topological derivative has been employed for image segmentation and restoration. The topological derivative-based segmentation uses two sparse matrices, and the computational complexity of thesegmentation grows up dramatically as the image size increases due to the…

Hierarchies and shape-space for pet image segmentation

Posted on February 2, 2016 by Matlab-Projects |

Positron Emission Tomography (PET) image segmentation is essential for detecting lesions and quantifying their metabolic activity. Due to the spatial and spectral properties of PET images, most methods rely on intensity-based strategies.…

Transfer Learning Improves Supervised Image Segmentation Across Imaging Protocols

Posted on February 2, 2016 by Matlab-Projects |

The variation between images obtained with different scanners or different imaging protocols presents a major challenge in automatic segmentation of biomedical images. This variation especially hampers the application of otherwise successful supervised-learning…
