We present a method of grouping edge elements upon the relation of smoothed continuity. This method is based upon the optimization of a quality function of curvature and edge intensity, from a local to a global level. It is implemented with a network of locally-connected processing elements. This method was rst designed to deal with dot images and then was applied to the problem of road extract...

High-spatial-resolution land-surface temperature is required for several applications such as hydrological or climate studies. Global estimates of surface are available from sensors observing in the infrared (IR), but without ‘all-weather’ capability. Passive microwave (MW) instruments can also be used to provide surface-temperature measurements suffer coarser spatial resolutions. To increase t...
