Novel Spectral Descriptor for Object Shape
In this paper, we propose a novel descriptor for shapes. The proposed descriptor is obtained from 3D spherical harmonics. The inadequacy of 2D spherical harmonics is addressed and the method to obtain 3D spherical harmonics is described. 3D spherical harmonics requires construction of a 3D model which implicitly represents rich features of objects. Spherical harmonics are used to obtain descrip...
متن کاملMultiscale Fourier descriptor for shape classification
The description of the object shape is an important characteristic of the image. In image processing and pattern recognition, several different shape descriptors are used. In human visual perception, the shapes are processed in multiple resolutions. Therefore multiscale shape representation is essential in the shape based image classification and retrieval. In the description of the object shap...
متن کاملMulti-scale embedded descriptor for shape classification
We present a new shape descriptor that are robust to deformation and capture part details. In our framework, the shape descriptor is generated by 1) using running angle to transforming a shape into a 2-D description image in the position and scale space. 2) performing circular wavelet-like sub-band decomposition of this 2-D description image based on its periodic convolution with orthogonal ker...
متن کامل3D Object Retrieval Using Compact Shape Descriptor
The need for effective and efficient 3D object retrieval approaches is emerging in a broad range of applications in science and engineering. With the increasing understanding of shape geometry and topology in the context of shape similarity, workable solutions for 3D object retrieval are being produced. In this paper, we present a novel technique for 3D Object Retrieval. The key idea of the pro...
متن کاملA New Shape Descriptor for Object Recognition and Retrieval
We present a new shape descriptor for measuring the similarity between shapes and exploit it in graphical object recognition and retrieval. By statistically integrating the local length-ratio and angle constraints between contour points relative to the shape skeleton, we construct the shape descriptor capturing the global spatial distribution of the shape contour. Then, the dissimilarity betwee...
