We propose a novel approach for head tracking, which combines particle filters with Isomap. The particle filter works on the low-dimensional embedding of training images. It indexes into the Isomap with its state variables to find the closest templat

Although accurate digital thermometers are now available at low cost, it remains exciting and instructive to build one your- self. The present circuit is particularly intended to help the reader in the use of a PIC processor Type PIC16F84 (
