安裝單個軟體包文件

安裝程式的首選方式是通過本章所介紹的軟體包管理器。然而，雖然 Ubuntu 軟體包庫非常大，但也有可能您想要安裝的軟體包並不在 Ubuntu 庫中。如果這樣的話，您也可以從網站下載並安裝文件。 在您安裝文件之前確認您所下載的文件來自一個安全的源是重要的。 有許多不同類型的 Linux 軟體包文件。它們多數與特定 Linux 發行版的軟體管理器相關聯。如 Debian 軟體包 文件 (.deb 文件)、Redhat 軟體包管理器 文件 (.rpm 文件) 和 Tarballs (.tar 文件)。 本部分內容將介紹如何安裝這些單個文件。 無法保證這些文件將與您系統相容，如果您安裝這些文件的話，您也將無法得到安全更新。有鑒於此，如果您想安裝程式的話，請儘可能通過軟體包管理器來安裝由 Ubuntu 自身提供的應用程式軟體包

2.5.1. 安裝/卸載 .deb 文件

這些是Debian 軟體包。這些與 Ubuntu 相關的軟體包文件使用 .deb 尾碼是因為 Ubuntu 與 Debian GNU/Linux 發行版有著緊密的關係。您將需要管理許可權來安裝 .deb 文件 (參見 第1.3.3節 ― root 用戶和 sudo 命令)。

• 要安裝 .deb 文件，簡單地雙擊它，然後選擇 安裝軟體包 即可。
• 或者，您也可以打開一個終端並輸入：
  • sudo dpkg -i package_file.deb 來安裝 .deb 文件。
• 如需卸載 .deb 文件，在您軟體包管理器中反選它，或輸入：
  • sudo dpkg -r package_name

Windows Vista: Disabling Services - Neowin Forums

Windows Vista: Disabling Services - Neowin Forums

I am not responsible for what you do to your Vista installation.

I suggest we use this thread to suggest to each other which services can be turned off, because we do not need them. This is a work in progress. I did not follow this post 100% and neither should you. Change services according to your computer config. If you do not have one of these services, chances are you already disabled the option in 'Turn Windows features on or off' or you are running a different edition of Windows Vista. Setting an Automatic service to Disabled will make sure it will not start when you boot up. Setting a Manual service to Disabled has no effect on performance and will only stop Vista from launching the service when it the OS believes it is needed.
Note: the default options are for Vista Ultimate. Some are obviously different.

A good application for saving presets of your services is: http://p-nand-q.com/download/pserv_cpl.html

Start > services.msc > Enter
Winkey + R > services.msc > Enter

Quick std::vector question - GameDev.Net Discussion Forums

Quick std::vector question - GameDev.Net Discussion Forums: "This is a good place to tell you to learn about smart pointers. They are objects that act like pointers, and logically 'own' the object, and are responsible for cleaning them up automatically. std::auto_ptr's are part of the standard library, but you can't use these in any of the standard containers. For a nice smart pointer (they are reference-counted smart pointers), learn about the boost.shared_ptr library."

Incremental auto-calibration of a single camera — Web Portal

Incremental auto-calibration of a single camera — Web Portal
A continuous and adaptive estimation of the vanishing points over thousands of images suppresses the amount of noise in their positions.

Project ideas

Incremental auto-calibration of a single fixed camera using facial images
Background:

1. Surveillance:
   
2. Moving objects are small
3. Not sure of critical motion
   

Goal

1. Estimate camera intrinsic parameters accurately
   

Technique

1. Facial Detection
2. Focal length estimation from 2 views
   
3. Incremental estimation from multiple views (f' = fold + r fnew)
   

To check:

1. Bias change by changing different R,t
   

UIUC Image Database : Car Detection

UIUC Image Database : Car Detection
This database contains images of side views of cars for use in evaluating object detection algorithms. The images were collected at UIUC by Shivani Agarwal, Aatif Awan and Dan Roth, and were used in the experiments reported in [1], [2].

The download package contains the following:

• 1050 training images (550 car and 500 non-car images)
• 170 single-scale test images, containing 200 cars at roughly the same scale as in the training images
• 108 multi-scale test images, containing 139 cars at various scales
• Evaluation files
• README file
