Smoothing of HMM parameters for efficient recognition of online handwriting

作者:

Highlights:

• An HMM based unconstrained online handwriting recognition is presented.

• A novel approach to smoothing of HMM parameters has been considered.

• A circular distribution is used to exploit the directional nature of input data.

• A fully connected non-homogeneous HMM is used.

• It is used for limited vocabulary recognition of unconstrained Bangla handwriting.
