A shape recognition scheme based on relative distances of feature points from the centroid
TLDR
The time complexity of the shape matching algorithm is O(m), where m is the number of feature points, and the most important advantage of the method is its independence to translation, rotation and scaling of objects.About:

Shape based leaf image retrieval
Zhiyong Wang,Zheru Chi,D. Feng +2 more
TL;DR: Experimental results on 1400 leaf images from 140 plants show that the proposed approach can achieve a better retrieval performance than both the curvature scale space (CSS) method and the modified Fourier descriptor (MFD) method.

Scale-invariant shape features for recognition of object categories
Frédéric Jurie,Cordelia Schmid +1 more
TL;DR: In this article, the authors introduce a new class of distinguished regions based on detecting the most salient convex local arrangements of contours in the image, which are used in a similar way to the local interest points extracted from gray-level images.

Robust shape similarity retrieval based on contour segmentation polygonal multiresolution and elastic matching
Emad Attalla,Pepe Siy +1 more
TL;DR: A novel shape similarity retrieval algorithm that can be used to match and recognize 2D objects using a new multi-resolution polygonal shape descriptor that is invariant to scale, rotation and translation.

A content-based image retrieval system
Chung-Lin Huang,Dai-Hwa Huang +1 more
TL;DR: A Content-Based Images Retrieval system which uses a modified geometric hashing technique to retrieve similar shape images from the image database and can accurately retrieve the similar images by using scaled, rotated, or mirrored sketched query images.

Shape Discrimination Using Fourier Descriptors
Eric Persoon,King-Sun Fu +1 more
TL;DR: A critical review is given of two kinds of Fourier descriptors (FD's) and a distance measure is proposed, in terms of FD's, that measures the difference between two boundary curves.

On the detection of dominant points on digital curves
C.-H. Teh,Roland T. Chin +1 more
TL;DR: A parallel algorithm for detecting dominant points on a digital closed curve is presented, which leads to the observation that the performance of dominant points detection depends not only on the accuracy of the measure of significance, but also on the precise determination of the region of support.

A Corner-Finding Algorithm for Chain-Coded Curves
TL;DR: A method for detecting sharp "corners" in a chain-coded plane curve is described and a measure for the prominence ("cornerity") of a corner is introduced.
