Free taken with digital cameras software for linux

Digital Camera Protocol is another command-line utility for DC21x cameras, this one looks and works just like "ftp" command. Not written by me, but uses some of my low-level Kodak code from digicam.

DigicaMerge project is a commandline tool to merge directories of pictures taken with digital cameras. If youve got a digital camera, your hard disk probably contains many directories full of pictures all named with the same names.
This utility allows you to merge such directories contents into a new directory, and renames all the pictures on the fly, ensuring no filename clash will occur.
You can define your own naming scheme, using either a set of predefined variables or any recognized Exif tag which may be present in your pictures, and also specify a pattern to select only certain files.
Installation:
- Extract it :
$ gzip -d digicamerge-x.xx.tar.gz | tar -xf -
where x.xx is digicamerges latest version number.
- Install it :
Go to digicamerges directory:
$ cd digicamerge-x.xx
Just type:
$ python setup.py install
You may need to be logged in with sufficient privileges (e.g. root)
This will generally install digicamerge in /usr/local/bin or an equivalent path depending on your system.
- Launch it :
Just type :
$ digicamerge
And read the long help message which contains examples.
Enhancements:
- A command line option was added to automatically remove duplicate pictures when merging directories.
- The manual page is now included in the package.

Python Traffic Analyzer is a Python base class and sample driver script written to retrieve and manipulate images from the TrafficLand cameras and calculate a numeric value representing the current traffic flow.

PyTrAn, an example driver script, an image collector and an image mask creator are available for download from the link shown at the bottom. To use the PyTrAn package begin by choosing a camera that you wish to analyze, for this example well use the camera captioned above.

We want to construct a mask over the area of the image that we are interested in, namely the road. In this particular example the road takes up the majority of the image but that is not always the case.

We will apply the mask over captured images to fine tune the area over which we are looking for movement. To create the mask we will first need to collect a sequential series of snapshots from the target camera. The image_collector.py script was written for this task:

$ mkdir mask_200003
$ cd mask_200003
$ ../image_collector.py 200003 30
Collecting 30 images...
30

Done.

The script is hard coded to capture images on a 2-second delay. The delay is necessary to ensure the image has changed. I believe 2-seconds to be the absolute minimum. Once complete, 30 images numbered 1 through 30 will be created in the current directory.

We construct a mask from these captured images by creating a diff-image for each sequential image pair and then adding each diff-image together. Naturally, a script was written to automate this task as well:

$ ../mask_maker.py 1 30
Creating a diff for each sequential image pair.
Diffing 29

Creating the initial mask from the first image pair.

Adding the rest of the diffs to the mask.
Masking 29

Done.

A number of .diff files are generated in this process. These files repesent the movement between individual sequence pairs.

The .diff files are simply intermediary files, the important bit is the mask file, which is generated as the sum of all differences.

The mask file may be dirty (as in this case) and require manual cleanup. The basic shape of the road however is clearly visible, evidence that we can with minimal effort automate the mask generation process. Also, this run was conducted at night, day-time images yield better results.

There are a few final steps we need to take before we can use the example PyTrAn driver script. First we need to convert the mask to ASCII (noraw) format:

$ pnmnoraw mask > mask_200003.ascii

Then we need to open an ImageMagick display window and get its X-window-ID using xwininfo. Finally, update camera_id and window_id in pytran_sampling.py and launch the driver:

$ ../pytran_sampling.py
DEBUG> grabbing frame from camera 200003
DEBUG> rotating image: pytran.this > pytran.last
DEBUG> refreshing image in 3 secs
taking a 5 minute sample at various thresholds.

5 minute sample[5]: 67.88
5 minute sample[10]: 42.66
5 minute sample[15]: 30.57
5 minute sample[20]: 23.03
5 minute sample[25]: 18.39
5 minute sample[30]: 14.79
5 minute sample[35]: 12.42
5 minute sample[40]: 10.53
5 minute sample[45]: 9.06
5 minute sample[50]: 7.85

The sampling script will take 5 minute samples at varying color thresholds. The optimal threshold must be manually chosen. Furthermore, you will need to sample the traffic ratios during both heavy and light traffic times to get a good feel for your acceptable range. Also, keep in mind that the traffic ratio value is simply the percent change detected, or in other words the movement detected within the masked region. This means that a completely empty road will register similar values to a road so congested it looks like a parking lot. The time of day can be combined with the traffic ration to determine the logical truth.

With this task implemented and abstracted more complex systems can be built. When I find the time Id like to create a system that will take multiple potential travel routes and times, and during the travel time e-mail the traveler with the best route to take. Another idea I had would be to record the traffic flow values for each camera, for each day and for each half hour interval. Travelers and other interested parties can then analyze traffic patterns to determine the fastest route dependant on date/time.

My Knoppix - Digital Home Edition is aimed to be a smart and centerised OS that can implement at home. Imaging you have a Plasma TV or big LCD screen that connect to a server and you can record and play DVD from the server and surf internet with big screen.

Video sharing using NX technology is also possible where you can play and watch different movies using different pc or pda at home. This CD also comes with videolan program where you can broadcast video or music throughout the network.

With the help of the NX technology, you can have a diskless PC that direct connect to the server and share application and files. Therefore server can play the movie on plasma tv while you can write document with openoffice using diskless pc that connect to the server.

DigiCam is a command-line interface to Kodak DC21x Digital Cameras. I own a Kodak DC215Zoom and its pretty shitty.

Ive compared images my camera makes with others, and I guess there is just something subtly screwed with my camera.

Focus mechanics or something. Ill probably dump this crap and get a real camera one of these days.

What you can do with it:

* Display camera or specific picture information;
* Display number of pictures in the camera;
* Delete any picture from the camera;
* Delete all pictures from the camera in one step;
* Take picture, save to file, delete picture from the camera in one step;
* Retrieve any picture and save to file;
* Retrieve all pictures, and save to current directory as imageNNN.jpg;
* Set resolution to High or Low before taking a picture;
* Set picture quality before taking a picture;
* Set Flash mode before taking a picture;
* Set Zoom value before taking a picture;

Run "cam" without any parameters for a complete list of possible options. Some options can be combined to make cam usable inside scripts. Please use common sense, and dont combine options like -d and -R, or -t and -d

Remote Capture for Canon PowerShot cameras project is a tool for controlling Canon PowerShot cameras.
The following cameras were reported to work with Capture. Please send a report to extend the list.
Canon PowerShot S50
Canon PowerShot A60
Canon PowerShot A70
Canon PowerShot A75
Canon PowerShot A80
Canon PowerShot A85
Canon PowerShot A95
Canon PowerShot A510
Canon PowerShot A520
Canon PowerShot G6
Canon Digital IXUS 400 (aka PowerShot S400)
Canon PowerShot S410
Canon PowerShot S500
The main advantage of Capture over gPhoto is that the consecutive shots are taken without the camera lenses being closed and opened again. When taking several thousand shots in a row, this indeed lets the camera live longer.
Enhancements:
- This release adds some minor enhancements and fixes.
- The code is stable.
