introduction: three-dimensional (3d) scanners are widely used in medicine. one of the applications of 3d scanners is the acquisition of anthropometric dimensions for ergonomics and the creation of an anthropometry data bank. the aim of this study was to evaluate the precision and accuracy of a modified 3d scanner fabricated in this study. methods: in this work, a 3d scan of the human body was o...

One-dimensional and three-dimensional piecewise chaotic maps are used to propose an image-encipher technique in this article. First, the logistic map is construct pseudo-random sequence. After that, sequence scramble plain image. Next, has produced a mask of doing some preprocessing steps on mask, bit-wise XOR operation with applied shuffled The suggested algorithm encipher decipher different r...

Ant-based clustering is a nature-inspired technique whereas stochastic agents perform the task of clustering high-dimensional data. This paper analyzes the popular technique of Lumer/Faieta. It is shown that the Lumer/Faieta approach is strongly related to Kohonen’s SelfOrganizing Batch Map. A unifying basis is derived in order to assess strengths and weaknesses of both techniques. The behaviou...

Among sonic interaction design practices a rising interest is given to the use of the voice as a tool for producing fast and rough sketches. Goal of the EU project SkATVG (Sketching Audio Technologies using Vocalization and Gestures, 2014-2016) is to develop vocal sketching as a reference practice for sound design by (i) improving our understanding on how sounds are communicated through vocaliz...

The purpose of this paper is to identify the effective points on the performance of one of the important algorithm of data mining namely support vector machine. The final classification decision has been made based on the small portion of data called support vectors. So, existence of the atypical observations in the aforementioned points, will result in deviation from the correct decision. Thus...

Empirical studies concerning face recognition suggest that faces may be stored in memory by a few canonical representations. In cortical area V1 exist double-opponent colour blobs, also simple, complex and end-stopped cells which provide input for a multiscale line/edge representation, keypoints for dynamic routing and saliency maps for Focus-of-Attention. All these combined allow us to segrega...

Motivated by a motion detection system the application of a new category of Kohonen‘s Self-Organizing Map (SOM) [8] is presented in this paper. Based on earlier work of Seiffert and Michaelis on three-dimensional SOMs [10], [11] a new implementation of growing multi-dimensional SOMs, the Quasi-Four-Dimensional Neuroncube (QFDN), has already been introduced in [12]. This paper focuses on the app...
