In this paper, a new 2D shape Multiscale Triangle-Area Representation (MTAR) method is proposed. This representation utilizes a simple geometric principle, that is, the area of the triangles formed by the shape boundary points. The wavelet transform is used for smoothing and decomposing the shape boundaries into multiscale levels. At each scale level, a TAR image and the corresponding Maxima-Minima lines are obtained. The resulting MTAR is more robust to noise, less complex, and more selective…

TLDR
A shape descriptor ρ(S) that is defined as the ratio of the squared distance between centroids and the squared diameter of shape S is studied, meaning in particular that value 1 is not taken, that 1 is the best possible upper bound, and and examples of shapes whose ρ (S) values are arbitrarily close to 1 are given.
