1 Abstract The ability of human beings to retrieve information on the basis of associated cues continues to elicit great interest among researchers. Investigations of how the brain is capable to make such associations from partial information have led to a variety of theoretical neural network models that act as associative memories. Several researchers have had signiicant success in retrieving...

Abstract: When a local operation is performed on the pixels in an array, the new value of the pixel is a function of the old values of the pixel and its neighbors. This paper introduces the more general concept of local operations on labelled dot patterns, where the new label of a dot is a function of the old labels of the dot and a set of its neighbors (e.g., its Voronoi neighbors). Such opera...

This paper presents an architecture for the efficient and high-speed realization of morphological filters. Since morphological filtering can be described in terms of erosion and dilation, two basic building units performing these functions are required for the realization of any morphological filter. Dual architectures for erosion and dilation are proposed and their operations are described. Th...

Morphological image processing filters preserve shapes related to the structuring element shape of the operator. The basic morphological operators are minimum (erosion) and maximum (dilation) operations performed on the pixels within a structuring element. Although these operators (and the compound operators formed from them) are able to smooth noise, they also introduce a statistical and deter...

A novel dynamic link architecture based on multiscale morphological dilation-erosion is proposed for frontal face authentication. Instead of a set of Gabor filters tuned to different orientations and scales, multiscale morphological operations are employed to yield a feature vector at each node of the reference grid. Linear projection algorithms for feature selection and automatic weighting of ...

Ground filtering is an essential step in airborne light detection and ranging (LiDAR) data processing various applications. The cloth simulation (CSF) algorithm has gained popularity because of its ease use advantage. However, CSF limitations topographically environmentally complex areas. Therefore, improved (ICSF) was developed this study. ICSF uses morphological closing operations to initiali...

A novel dynamic link architecture based on multiscale morphological dilation-erosion is proposed for frontal face authentication. Instead of a set of Gabor lters tuned to diierent orientations and scales, mul-tiscale morphological operations are employed to yield a feature vector at each node of the reference grid. Linear projection algorithms for feature selection and automatic weighting of th...
