Projects

Face Recognition via Sparse Representation

. Mainly using the well-known l1-norm constrained least-square

reconstruction minimization technique to realize face recognition.

The training set is constructed as follows: each subject is presented

in the training with many images representing various lighting

conditions, so that a probe image (testing image) of certain

illumination conditions can be represented by a sparse linear

combination of the training samples.

Audio Graphic Equalizer:

. The system decomposes the input into high frequency and low frequency

components by using linear phase high-pass and low-pass filters.

Different gains are introduced to the filter outputs to emphasize or

attenuate the corresponding frequency band components. The resultant

signals of the two channels are added together to form the final

output.
