Tissue Image Processing
Jacky Tay
This project looks at the relationship between various multifractal measures of cell structures
in tissues and the corresponding pleomorphic scores assigned by pathologists. The Holder exponent of local intensity
variations is used to identify Mitotic cellsPublications:

Facial Expression Representation
Mohammad Obaid
Quadratic deformation models are applied to motion capture
data to obtain generic transformation parameters that represent
different types of facial expressions. These
parameters can then be used to transfer the expression to two or
three dimensional models.Publications:

representing certain shape characteristics of tissue and cell
images using multifractal spectra.

Facial Expression Animation
Jacky Tay
Muscle regions are automatically mapped to a
two-dimensional sketch based model or an image, based on primary
feature points, and then deformed using rubber-sheet
transformation coefficients derived for a given facial
expression. The model is animated by interpolating the
transformation coefficients from the neutral expression to the
given expression for each muscle region. Additional facial features are added for
enhancing the realism of the generated facial animation
sequence.

J2ME Computer Vision
Library for Mobile Devices
Jian Gu
This research explores the feasibility of using Java (J2ME)
to develop cross platform computer vision applications for
mobile phones with integrated cameras. Several AR applications
on J2ME enabled mobile phones are developed and tested using the
library. Experiments are conducted to evaluate the
compatibility, portability and efficiency of vision algorithms
and functions implemented in the
library. Publications:

Fast Algorithm for
Painterly Rendering on Mobile Devices
Charles Han
A low-complexity painterly rendering algorithm suitable for implementation on mobile devices
is developed. A sequential connected component labelling algorithm is used to represent regions
of similar color in an index buffer and a color table. All subsequent processing is done on the
index buffer to minimise computational complexity. Publications:

Radial-Tchebichef Invariants for Pattern Recognition
R Mukundan
A new class of global shape descriptors based on Tchebichef
polynomials is developed for applications in pattern
recognition. The definition of Radial-Tchebichef moments
is very similar to Zernike moments, except that the kernel
functions are discrete orthogonal polynomials. Rotational
invariants can be easily derived from these moment functions
because of their radial-polar structure.Publications:

Geometric Moments Using Schlick's Approximation
R Mukundan
A modified version of normalized geometric moments can be
created by using Schlick's approximation for the exponential
terms. Schlick’s approximation is useful in significantly reducing the computational
time required for evaluating the moment kernel. The modified moments have a better dynamic range of values,
particularly for high orders.Publications:
