Welcome to the updated icpc gallery. All official photos from ICPC World Finals are stored here. If you would like to contribute your photos, email to [email protected].
Select a year! Selector is located on the left on desktop and in the upper menu on mobile/ By default, when selectin a year with no other filters preset, you will enter a Photo Tour.
Photos from each year are classified into multiple events. Select the appropriate event in the Events filter. Some noteworthy filters are Opening Ceremony. Team Photos, World Finals and Closing Ceremony.
Pictures may have specific teams tagged in them. Select the team name from the list (or type a few letters to narrow your search) to get all images of that team in the selected year.
To select the images with recognised individuals, pick a name from the list of suggestions, or type a few letters to narrow your search.
To search by a keyword just type it into the Search field. For example, Bill, Opening or Champions
The gallery is built on top of the flickr api backend. All metadata is stored in photo exif tags. Tag types are:
- year, for example
album$2001 - event, for example
event$Team Photos - team, for example
team$Aalto University - person, for example
Bill Poucher(1761524d3f579a4d). The data in parenthesis denotes face location within the image in Picasa standard.
The 16 characters enclosed in rect64(…) is a 64-bit hexadecimal number which can be broken up into four 16-bit numbers used to identify the position of the rectangle used to mark the face.
If you divide each of the four 16-bit numbers by the maximum unsigned 16-bit number (65535), you’ll get four numbers between 0 and 1 which give the relative coordinates for the face rectangle in the order: left, top, right, bottom.
To calculate the absolute coordinates, multiply the left and right relative coordinates by the width of the image and multiply the top and bottom relative coordinates by the height of the image. This way the faces will always be identified even when the image is re-sized.
Even though flickr stores tags in their initial form, it is important to remember the following
- by default, manually entered tags are split into separate words. Enclose the tag in quotes
"team$Aalto University"to keep tag intact - flickr eliminates all spaces and non-letter sybmols from tags for the filtering purposes
- make sure to keep correct encoding on tags, specifically in people names, to consistently process diacritic symbols
- make sure to enclose all university names with punctuation in quotes
src/const.js contais access detail and general year setup.
Each year separately can be setup through individual year files in /public/.
