It was found by experimentation, that to maximize the recognition rate we have to have use around 20 key Points and compute the Zernike moments from or-der 1 to 12 on an 11x11 pixels neighborhood around each key Point

Notice that the program is able to rec-

ognize the objects correctly.

The Different phases involved in the

recognition process.

1.Harris Key Points

2.Zernike Moments

Testing different combinations

of key points & Zernike Moments
