Shape Recognition Based on Projected Edges and Global Statistical Features

Table 3

Experimental results of the proposed GSPPED shape descriptor and the two-level classification algorithm including the AL-NN classification. Test sets A-D contain shape images from live tests performed with participation of visually impaired subjects; test set E was generated in laboratory.
