Kernel descriptor based plant leaf identification
Plant identification is an interesting and challenging research topic due to the variety of plant species. Among different part of the plant, leaf is widely used for plant identification because it is usually the most abundant type of data available in botanical reference collections and the easiest to obtain in the field studies. A number of works have been done for plant leaf identification. ...
متن کاملNovel 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 کاملGlobal Binary Patterns: A Novel Shape Descriptor
In this paper, we propose a novel shape descriptor, called Global Binary Patterns (GBP), based on interpreting intensity values along a direction in an image as binary numbers, converting these binary numbers to their decimal values and concatenating these decimal values as the elements of a vector that is the GBP representation of the shape. Comparing with some widelyused state-of-the-art meth...
متن کاملNurbs: a New Shape Descriptor for Shape-based Image Retrieval
The representation, matching and analysis of objects of interest are of prime importance in shape-based retrieval systems. In the large image repositories, there arises a problem to find a set of images that are relevant to the user’s needs. This necessitates an effective retrieval approach that resembles the human capability to retrieving images that are relevant to a query from a database. Pe...
متن کاملTemplate Based Shape Descriptor
We introduce a new 3D shape descriptor which maps the surface features onto an arbitrary template surface using mean-value interpolation. A compact numerical shape descriptor is extracted using manifold harmonics on the template. We show that mean-value interpolation is a strong alternative to the often used projection. The utility of using different templates is established by showing that con...
