A rational methodology
for lossy compression- REWIC is a software-based
implementation of a a rational system for progressive transmission which, in
absence of a priori knowledge about regions of interest, choose at any
truncation time among alternative trees for further transmission. To
circumvent the lack of knowledge of what distortion measure is more suitable
for optimization of the trade-off between image fidelity and coding rate, this
coder shall introduce a novel mathematical methodology for rate control by
organizing the progressive transmission in accordance with coherence
constraints for avoiding forms of behavioral inconsistency. A set of
postulates is provided for specifying the ways in which preferences need to be
made precise and fit together if illogical forms of behavior are to be
avoided. We show that the rational choice for transmission at truncation time
t is to select bit streams which have the maximum expected increase in utility
per coding bit, where ``rational‘‘ must be understood in the sense that it
cannot lead the transmission system into forms of behavioral inconsistency.
This method is then used within a progressive transmission scheme to produce a
new compression method called rational embedded wavelet image coding
(REWIC). (byJ.A.Garcia,

Collective rationality
for the allocation of bits- CORAL is a software-based
implementation of a new coder scheme that in absence of a priori knowledge
about regions of interest propose a new method for bit allocation which can be
used with reasonable internal consistency and acceptable image
fidelity. The effectiveness of a coding method can be improved
through a space-varying filterbank tree representation of the image, and this
property can be conveniently exploited using appropriate bit allocation
strategies among the spatial segments of the image. In CORAL we examine the
conditions for achieving a rational agreement on the distribution problem by
stating axioms that its solution must obey in absence of a priori knowledge
about regions of interest. Firstly, a measure of benefit avoiding certain
forms of behavioral inconsistency is to be assigned to each possible bit
allocation in such a way that each region‘s preference may be inferred between
any two bit allocations from their respective benefits. Secondly, individual
regions are to agree on an allocation of bits which is then to be brought
about by a joint strategy, but, under what conditions is their agreement
rational? CORAL propose a characterization of rational agreement whose
solution is an application of a general procedure for cooperative action where
each may benefit only on terms which permit proportionately equal benefits to
others. Experimental results are given to evaluate the performance of the
strategy of COllective Rationality for the ALlocation of bits (CORAL), based
upon a validated predictor for visual distinctness from digital
imagery. (by J.A.Garcia,

Gandalf -
Gandalf is a computer vision and numerical algorithm library, written in C,
which allows you to develop new applications that will be portable and run
FAST. Includes many useful vision routines, including camera calibration,
homographies, fundamental matrix computation, and feature detectors (includes
source code). Dynamically reconfigurable vector, matrix and image
structures in Gandalf allow efficient use of memory. Gandalf has been used to
develop the "MoKey" motion editing software, released at IBC‘2001 in
Amsterdam. MoKey performs automatic inpainting of moving objects over an image
sequence, and can also be used to compute an accurate alpha matte or outline
of an object. Gandalf currently contains four packages: 1) Common package of
simple structures and routines used by the other packages, such as memory
allocation, linked lists and error handling; 2) Linear algebra package with a
large number of routines for matrix and vector manipulations; 3) Image package
defining a general purpose image structure and low-level image manipulation
routines; 4) Vision package containing a number of standard image processing,
computer vision and numerical routines. The major design features of Gandalf
are: (i) Efficient use of memory through dynamically reconfigurable
structures; (ii) Emphasis on support of numerical algorithms, especially
optimisation; (iii) A very flexible and efficient internal image
representation, (iv) A comprehensive set of matrix/vector operations,
incorporating implicit matrix transpose & inverse, and in-place
computation where appropriate; Exploitation of the computational and
compilation speed advantages of C over C++ in reducing the number of layers of
abstraction over the raw data, an approach we believe is appropriate for
simple objects such as matrices, vectors and images. The documentation for
Gandalf comes in two parts. There is a LaTex tutorial with examples available
also in HTML (via Latex2html). Reference documentation for Gandalf has also
been generated using ObjectOutline, (by Philip McLauchlan /Imagineer

Segmentation of
Skin-Cancer Images- Implementation of an algorithm for
segmenting images of skin cancer and other pigmented lesions (see Image and
Vision Computing, January 1999, pp. 65-74). An automatic method for
segmention of images of skin cancer and other pigmented lesions is
implemented. This method first reduces a color image into an intensity image
and approximately segments the image by intensity thresholding. Then, it
refines the segmentation using image edges. Double thresholding is used to
focus on an image area where a lesion boundary potentially exists. Image edges
are then used to localize the boundary in that area. A closed elastic curve is
fitted to the initial boundary and is locally shrunk or expanded to
approximate edges in its neighborhood in the area of focus. Segmentation
results from twenty randomly selected images show an average error that is
about the same as that obtained by four experts manually segmenting the
images. (by L.

Texture Synthesis
and Analysis by Rupert Paget- Fast texture synthesis by
nonparametric MRF modelling. Source code is provided, plus many free
textures. Fast Semi Causal Nonparametric Markov Random Field Texture
Synthesis. This algorithm is a cut down version of the algorithm published in
IEEE Transactions on Image Processing 1998. In this version, it has been
rewritten for a single cpu machine. To maintain speed of synthesis, the update
function UpdateFn() has been set to return the maximum value. If this was
modified to return a portion of the maximum value, then the synthesis would
take longer, but there would be a gain in quality. If you do decide to modify
the code, be careful, as I have not put in any safeguard checks. Best to fully
understand the whole code, before modifying it. Recently there has been quite
an influx of nonparametric sampling techniques for texture synthesis, this is
because it has been the nonparametric models that have had the greatest
success at synthesising arbitrary textures. This technique uses a multiscale
approach, which has the advantage that only a small neighbourhood is required.
This fast version implements a modification based on Ashikhmin‘s Synthesizing
Natural Textures. As noted in his work, the L2 norm may not be the best
measure to test for perceptual similarity between two neighbourhoods. Instead,
we may note that if we are only taking pixels from the input image (and not
sampling from a larger distribution), then when we iterate a respective pixel,
we can be assured that each of its defined neighbours occur within the input
image. Speed can be gained if, instead of doing a exhaustive search, we only
sample from those pixels which have the same neighbour. In this algorithm I
have modified Ashikhmin‘s approach by using our previous algorithm, and
sampling from all pixels which have at least one of its neighbours the same
colour as its respective neighbour of the pixel being iterated. This algorithm
works well for natural textures which have a pixelwise noise
distribution. (by Rupert
