The problem of finding the relative position and orientation between the reference frames of a link-mounted sensor and the link has been formulated as a kinematic equation of the form Hlx= Hxcin terms of homogeneous transformation matrices by Shiu and Ahmad (1987). In this article, normalized quaternions (Euler parameters) are used to transform the(More)
The essential oil obtained by hydrodistillation from the aerial parts of Tunisian endemic Hypericum triquetrifolium Turra (Clusiaceae) was analyzed using GC and GC-MS. One hundred and nine compounds consisting of 92.2% of total detected constituents were identified. Sesquiterpene hydrocarbons were the main constituents (59.37%), Alpha-humulene,(More)
Abs t rac t The problem of finding the relative orientation between the reference frames of a link-mounted sensor and the link is formulated as a kinematic equation of the form A , A , = A,&, which has to be solved for the rotational transformation matrix A , given the transformations A , and Ab. This equation can be transformed to i ts equivalent form in(More)
In this paper, we proposed hardware architecture for the most complicated bloc in the standard of video coding H264, it is the block of motion estimate and compensation. The proposed architecture has the advantage of gaining in the computation time and memory space for recording images, and even the advantage of keeping the same memory addresses for the(More)
High-level vision systems that use range images require them to be segmented into clusters of pixels with a common geometric representation. This paper presents a new range image segmentation technique based on successive differentiation. Each time the image is differentiated, an edge detection process follows to locate the surface jump and fold(More)
