Description: 一个基于图形的高效图像分割算法，包括论文及相应的源代码。-This paper addresses the problem of segmenting an image into regions. We define a predicate for
measuring the evidence for a boundary between two regions using a graph-based representation of the image. We
then develop an efficient segmentation algorithm based on this predicate, and show that although this algorithm
makes greedy decisions it produces segmentations that satisfy global properties. We apply the algorithm to image
segmentation using two different kinds of local neighborhoods in constructing the graph, and illustrate the results
with both real and synthetic images. The algorithm runs in time nearly linear in the number of graph edges and
is also fast in practice. An important characteristic of the method is its ability to preserve detail in low-variability
image regions while ignoring detail in high-variability regions

Description: The objectives of Partial Differential Equation Toolbox™ software are to
provide you with tools that:
• Define a PDE problem, e.g., define 2-D regions, boundary conditions, and
PDE coefficients.
• Numerically solve the PDE problem, e.g., generate unstructured meshes,
discretize the equations, and produce an approximation to the solution.
• Visualize the results.-The objectives of Partial Differential Equation Toolbox™ software are to

Description: This example application shows you how to use Real-Time Workshop Embedded Coder to target a dual core Blackfin microprocessor. The complete build is managed by a template makefile and control over the memory regions is provided by custom storage classes. The example imposes a top level architecture on the model to define the split of model code between the two cores. This document describes a complete run-through of the model from Simulink simulation to code simulation using VisualDSP. I think it will take about 1 hour to go through the example once you have VisualDSP installed.

Description: VisualBasic 的 HMM 范例
HMM模型，Viterbi，滑动窗算法唐纳 Helland（定位在人类的DNA基因的目的)-HMM、Viterbi、and Sliding Window Algorithms (for purposes of locating genes in human DNA) by Tanner Helland
This project demonstrates use of a Hidden Markov Model (HMM) to define the relationship
between normal states (B) and island states (I) within a region of the human chromosome.
This algorithm proves particularly useful for gene finding、as CpG islands (regions of DNA
with a larger than expected number of adjacent cytosine and guanine nucleotides) tend to
appear near the promoters of some 40 of mammalian genes. The automation of this process
is critical in gene research because CpG islands are impossible to locate by simply looking
at a strand of DNA (as they may cover several hundred bases and their C/G content may be
only slightly higher than the expected value).
The algorithm is fast、robust、and it includes a wealth of good routines (such as loading FASTA
files into VB). Ive tried to include comments where applicable.
