configure your opencv environment first

this project tested on VS2010

-----------------------------------------------------------------------

- most of the code should also work with Linux (except for the GUI), I

hope to do a port in the next month or so.

- code not tested with 64-bit Windows or Linux.

- for Visual C++ .net (2003), you should use

code/projects/mfc_projects_net/thesis_interface/thesis_interface.sln

- edit file code/pc_system_info/local_data.h so that:

sequences_directory points to the full pathname of the sequences directory

code_directory points to the full pathname of the code directory

- edit file code/cpp/commands/chamfer_script.txt so that

c:\users\athitsos\sequences\original.avi is replaced by the full path

name of sequences\test\original.avi (use backslashes in the path,

since we are running on Windows).

- add directory code/dlls to your system path (edit the PATH

environment variable).

----------------------------------------------------------------------

- after compiling the code, run. You should get a dialog window, and a

console window. At first, the dialog is active and the console is

inactive.

- In general: when the dialog is active, press the '=' key

on the keyboard to make the console active. When the console is

active, type

x

and press

to make the dialog active.

- to quit the program, make the dialog active, and press key 'q'.

- when the program starts, press '=' to make the console active.

- type

file chamfer_script

You should get the following output:

########### beginning of output #####################

minimum = 10.432643

########### end of output #####################

- now, if you type

x

and press , to make the dialog active, you should see an edge

image, that represents the second nearest neighbor of the query in the

database. While the dialog is active, press:

- key '1' to see the first nearest neighbor of the query:

- key '3' to see the edge image of the query

- key '4' to see the actual query.

----------------------------------------------------------------------

there is not much documentation for the code. As you try to figure it

out, the main starting points should be:

- file code/cpp/commands/chamfer_script.txt

Any line in that script is a line that you can type into the console,

while the console is active.

- files code/cpp/gestures/thesis_module.cpp and

code/cpp/gestures/graphics_module.cpp. In both those files, look at

the enter_command function. This function associates commands that

you can type on the console (like the ones in chamfer_script.txt)

- commands "database_create" and "database_load_distances" load up the

entire database into memory, and also load for each image the

associated distance transform.

- command "add_input" opens a sequence and displays it on the dialog

window. The same effect can be accomplished by using the dialog,

clicking on the "load" button, and selecting a sequence.

- when a sequence is displayed, and the current image is a segmented

image of a hand, then (while the console is active) command "canny

50" performs canny edge detection with threshold 50. Then,

"database_chamfer_distances" computes the distance between the edge

image and all database edge images. Then, "chamfer_rank k" (k >= 1)

displays the k-nearest neighbor of the query in the database, and

prints out the corresponding chamfer distance.

----------------------------------------------------------------------

database format:

- 20 hand shapes.

- for each hand shape, we save images from 84 different

viewpoints. Therefore, the database contains 1680 images. All images

are normalized so that the size is 256x256, and the actual edge

image is centered so that its minimum enclosing circle has center

128,128 and radius 120.

- the viewpoints that were used are saved in

sequences/poser/viewpoints.txt. Each viewpoint is specified by two

numbers. To interpret those numbers, think of the hand as positioned

in the center of a sphere, and the camera being positioned on the

surface of the sphere and pointing to the center. The north pole of

the sphere is such that the camera is pointing to the back of the

palm and the south pole is such that the camera is pointing to the

back of the palm. For viewpoint (x1, x2), x1 is the north-south

position of the camera (-90 is north, 90 is south, 0 is equator),

and x2 specifies the east-west position (0 is such that the fingers

point to the right, and as the value increases, the camera is moving

towards the east).

- we do not explicitly save images for different image plane rotations

of the same shape/viewpoint combination, but such images can easily

be generated on the fly. To see such an image, type (while the

console is active):

database_edges 1432 21

Then (you may need to make the dialog active to actually see the

image) you will see the image corresponding to the 21st rotation of

frame 1432 of the database. Rotations range from 0 to 47, and frames

range from 0 to 1679. Rotation 21 corresponds to rotating the original

frame by 21 * 7.5 degrees.

- Any query image is matched with each database frame (i.e., each

handshape/viewpoint combination) at 48 different orientations, so

that in total we match the query to 80640 images.

- Computing chamfer distances is done pretty efficiently, by

precomputing 48 distance transforms of the query (corresponding to

each of the 48 different image-plane rotations of the query) and

having in memory the distance transforms of all 1680 frames of the

database. However this takes up a lot of memory. If you plan to use

a larger database, then the more standard definition of the chamfer

distance should be used (as described in our CVPR 2003 paper), which

is much slower, and then embeddings can be used to speed that

up.

yet, I do hope to incorporate such an implementation in the next

couple of months.

- you can view the edge images from the database by opening (from the

dialog, clicking on the "load" button) sequence

sequences/poser/selected_asl_edges.rle. In that same directory, you

can also load the distance transforms (selected_asl_dt.vimseq1), the

original images generated by the Poser 5 graphics software

(selected_asl_colors.rle) and a cartoon rendering of those images

(which I used to generate the edges) at

selected_asl_cartoons.rle. Note that the _colors and _cartoon

sequences show a left hand (that is what Poser generates), whereas

the edge images show a right hand (obtained by flipping the original

images upside/down).

- the test images are in sequences/test. File edges.rle contains

normalized edge images. File original.avi contains unnormalized

color images of hands (the hands have been segmented and the

background is black). File classes.txt specifies the class of the

handshape in each frame. In the database, the first 84 frames

correspond to class 0, the second 84 frames to class 1, and so on.

- video formats .rle and .vimseq1 are my own formats, so the only

WINVER not defined. Defaulting to 0x0502 (Windows Server 2003)

url : http://mnslaboratory.springnote.com/pages/872002

Visual C++ 개념: 이식 및 업그레이드

WINVER 수정

Visual C++ .NET의 이전 릴리스에서 MFC 프로젝트를 작성할 때 프로젝트가 WINVER에 대해 다른 값을 사용하기 때문에 컴파일 오류가 있을 수 있습니다.

Visual C++의 이전 버전에서 프로젝트를 만들 때는 WINVER가 400으로 설정되어 Windows 95나 Windows NT 4.0에서처럼 Platform SDK 헤더 파일의 이전 버전을 사용하여 컴파일할 수 있었습니다.

다음 중 한 가지 방법을 사용하여 WINVER=400을 암시적으로 설정했을 것입니다.

Visual C++ 6.0의 최초 버전과 함께 사용할 수 있는 Platform SDK 헤더 파일의 이전 버전 사용

Visual C++ 6.0 프로젝트에 winres.h 포함. 이 파일에는 WINVER를 400으로 정의한 내용이 포함되어 있습니다.

이 두 가지 방법 중 하나로 WINVER=400을 설정한 경우, WINVER=400을 아직 설정하지 않은 경우, Visual C++ .NET의 프로젝트에서 컴파일러 오류가 발생되는 경우, 명시적으로 WINVER=400을 정의해야 합니다. 예를 들면 헤더 파일에 다음 코드를 추가할 수 있습니다.

#define WINVER 0x0400

또는 [속성]-[C/C++]-[전처리기]-[전처리기 정의]에 추가

;WINVER=0x0500
