3D Object Recognition by Classification Using Neural Networks

Journal of Software Engineering and Applications 2011年第5期4卷 306-310页

In this Paper, a classification m.thod based on neural networks is presented for recognition of 3D objects. Indeed, the objective of this paper is to classify an object query against objects in a database, which leads to recognition of the form.r. 3D objects of this database are transform.tions of other objects by one elem.nt of the overall transform.tion. The set of transform.tions considered in this work is the general affine group.

The size of 3D data stored around the web has becom. bigger. Therefore the developm.nt of recognition applications and retrieval system. of 3D m.dels is im.ortant. This paper deals with invariants for 3D m.dels recognition. Thus under general affine transform.we propose in a first tim. determ.nants of three points to realize invariance under affinity. To solve starting point problem.we needs Fourier Series (FS) to extract affine invariant descriptors, called Fourier Series Descriptor (FSD). The difference between first and second approaches: in first approach determ.nants are com.uted on cartesian coordinates directly while in the second one determ.nants are com.uted from.FS coefficients to elim.nate dependency on starting point. The FS are also applied on 2D slices to generate affine invariants for 3D volum.. FS can be com.uted based on hole points of volum., but this technique. The principal advantages of proposed approaches is the possibility to handle affine transform.and 3D volum.. Two types of 3D objects are used in the experim.ntations: m.sh and volum., the Princeton Shape Benchm.rek (PSB) is also used to test our descriptor based on FSD.

Lym.hatic m.lform.tion (m.), form.rly called cystic lym.hangiom. is a benign ham.rtom.tous tum.r of lym.hatic vessels. The onset of lym.hangiom.s is either at birth (60% to 70%) or up to two years of age (90%) and rare in adults. These m.lform.tions can occur in any region of the body, Lym.hangiom.s have m.rked predilection for the head and neck region (50% - 70%). The m.st com.on location in the m.uth is the dorsum.of tongue. If the positive diagnosis is generally easy, the therapeutic m.nagem.nt rem.ins controversial. We report the clinical case of a 23-year-old adult patient with cystic lym.hangiom. on the floor of the oral cavity extending gradually to the right subm.ndibular region. The clinically suspected tum.r was thoroughly explored using tom.densitom.try. The treatm.nt consisted of com.lete resection by a cervicotom. with histological exam.nation confirm.ng the m.croscopic diagnosis of cystic lym.hangiom.. Follow-up at 3 years showed no recurrence.
