Blooming flower recognition by using eigenvalues of shape features

This paper introduces the concept of eigenvalues in describing the shape features of blooming flowers, and implements the idea in recognizing the blooming flowers automatically. The input images of blooming flowers are taken from natural scene in the form of RGB images. The proposed method first segments and crops the targeted flower object, then calculates four shape features to form a 2 × 2 matrix. Eigenvalues of the matrix computed from...
