To get started with this blank TiddlyWiki, you'll need to modify the following tiddlers:
* SiteTitle & SiteSubtitle: The title and subtitle of the site, as shown above (after saving, they will also appear in the browser title bar)
* MainMenu: The menu (usually on the left)
* DefaultTiddlers: Contains the names of the tiddlers that you want to appear when the TiddlyWiki is opened
You'll also need to enter your username for signing your edits: <<option txtUserName>>

Web 2.0 Principles and Best Practices
Finally, in the interests of public education, it's worth noting the eight core patterns of Web 2.0 listed in the report, and which I've tried to put meaningfully in the visualization above: 

    * Harnessing Collective Intelligence: Sometimes described as the core pattern of Web 2.0, this describes architectures of participation that embraces the effective use of network effects and feedback loops to create systems that get better the more that people use them.
    * Data is the Next "Intel Inside": A phrase that captures the fact that information that information has become as important, or more important, than software, which has become relentlessly commoditized.
    * Innovation in Assembly: The Web has become a massive source of small pieces of data and services, loosely joined, increasing the recombinant possibilities and unintended uses of systems and information.
    * Rich User Experiences:  The Web page has evolved to become far more than HTML markup and now embodies full software experiences that enable interaction and immersion in innovative new ways.
    * Software Above the Level of a Single Device: Software like the horizontally federated blogosphere (hundreds of blog platforms and aggregators) or the vertically integrated iTunes (server farm + online store + iTunes client + iPods) are changing our software landscape.
    * Perpetual Beta: Software releases are disappearing and continuous change is becoming the norm.
    * Leveraging the Long Tail: The mass servicing of micromarkets cost effectively via the Web is one of the primary "killer business models" made possible by the Internet in its present form.
    * Lightweight Software/Business Models and Cost Effective Scalability: Everything from Amazon's S3, to RSS, to Ruby on Rails are changing the economics of online software development fundamentally, providing new players powerful new weapons against established players and even entire industries.

d2: the duration of the first note in the next slope

let (446)-30(480)-40(480)-10(480)-20 be the detailed note durations and note pitches for a slope, e.g. 446 duration of the first note, and relative pitch is -30. With the format above, d1 = 446, feature = -30(480)-40(480)-10(480)-20

Clint's fix for weird IE behaviour
body {position:static;}
This assignment will try to solve the problem of content-based image retrieval

My step:
#Download and extract the zip files
#Copy the imageset folder to D:\ for convenience

Notes for the source code:
- Cimg.h and Cimg.cpp: 2 main files here for image comparison
- ImgSim, ImgSimDlg, SecondaryDlg used for providing a simple GUI (perhaps we need to modify these things as well, using c++ MFC)

Members & functions in CImg.h:
*const int ZIGZAG: for traversing the array in zig-zag order
*struct S_resized_samp: have 3 members: Y, cr, cb for YCrCb color space
*struct Sintg_hist : for integer histogram (int numbin and int* bins)
*struct SYCrCb_his : for color histogram in YCrCb (int numbin and double* bins)
*pblockarr: JBLOCKARRAY[3]: for Y, Cr, and Cb - Store the DCT block in YCrCb color space
*pnBlkHeight and pnBlkWidth is array[3], corresponding to pblockarr. The first  member refers to Y component, other 2 refer to the Cr and Cb component.
*num_comp = 3 number of components in an image = 3 (Y, cr and Cb)
*n_size = pnBlkHeight[1] * bnBlkWidth[1] -> For Cb component: number of block
*struct S_resized_samp res_image[n_size]: perhaps the DC value of DCT block (Y, Cr,Cb) component
*s_resized =  n_size


To check whether an DCT block represent an edge or not, we may not want to tak into account of Y[0][0], Cr[0][0] and Cb[0][0]
