....is not seen as an erosion followed by a dilation, but rather as the supremum of translated versions of a function . Although all these algorithms were developed for a function they are applicable to binary openings. Algorithms dedicated to binary openings have also been proposed. VAN VLIET [12] et al. SCHMITT [7] and later VINCENT [13] provided methods which analyze the border of both and . LAY [5] developed an algorithm based on the distance function. The geometric interpretation, that an opening is the union of translated . included in , led VAN DROOGENBROECK [9] to propose a ....

....approaches to improve 2D algorithms have been reported. All of them use a more suitable representation of the image data to improve the performance. Boomgaard and van Balen [14] use a bitmap representation of binary images because the CPU operates on 32 pixels in parallel. Verwer and van Vliet [15] use a queue of the contour pixels to avoid traversing all the image each time. Parker [8] uses maps of distance and Young et al. 16] used a run length representation of the image. There are also 3D approaches. Zuiderveld [17] proposes a method for successive dilation operations of 3D images by ....
....time. Parker [8] uses maps of distance and Young et al. 16] used a run length representation of the image. There are also 3D approaches. Zuiderveld [17] proposes a method for successive dilation operations of 3D images by using a queue of contour voxels, following the idea of Verwer and Vliet [15]. Nevertheless, this proposal demands an overhead of memory. Thurfjell et al. 12] proposes a method for fast erode and dilate using the semiboundary representation [13] These two proposals only traverse the contour n voxels in the 3D data set. However, they can not use structuring elements of ....

....operator is closely associated with the notion of connectivity. It also implies that the action is based on a kind of growing process, where the information is propagated through the image. The wave front propagation interpretation of morphological operations was pionered by Van Vliet and Verwer [8]. In wave front propagation algorithms, the following aspects can be distinguished: Gamma selection of the initial wave front (i.e. which pixels are selected for processing) Gamma selection of the points to which a point on the wave front is propagated. i.e. the elementary wave front) It ....

.... (for example in seed propagation) only the pixels belonging to the external contour of binary objects are involved: the list of these pixels can be obtained easily from the previous iteration, increasing the overall performances by applying the dilation only to border pixels (contour processing [41]) 2.2 Parallel architectures Two different parallel systems will be considered in the following: architectures which distribute a single elaboration among different Processing Elements (PEs) implementing operational parallelism, and architectures which subdivide the processing of the whole ....
