Applications
-
Handwritten character recognition
Prototype formation
-
Average curve computed by averaging
corresponding segments
-
Useful in many applications like computational atlases, comparing anatomical
structures, recognition


Morphing
-
Can generate morph sequences for shape that are not very dissimilar

Handwritten character recognition
-
Compute the prototype for each category
-
Match each query to all prototypes and find the nearest neighbor
-
For 327 characters we get 99% recognintion rate
Object recognition
-
Curve matching framework works well in the presence of affine transformations,
and visual transformations
-
We get acceptable classification rates for a database of 36 shapes (6 categories,
6 shapes each)
-
Five nearest neighbors are from "correct" category (36, 35, 35, 33, 27)
-
We get acceptable classification rates for a database of 99 shapes (9 categories,
11 shapes each)
-
Ten nearest neighbors are from "correct" category (99, 97, 97, 98, 94,
94, 90, 84, 74, 50)
