Efficiently querying geospatial data, however, is a considerable challenge: because the data is two-dimensional (or sometimes, more), you can't use standard indexing techniques to query on position. Spatial indexes solve this through a variety of techniques. In this post, we'll cover several - quadtrees, geohashes (not to be confused with geohashing), and space-filling curves - and reveal how they're all interrelated."<br/> <p><strong>Tags:</strong> #algorithms #databases #geo #hilbertcurves #indexing #quadtrees #spatial</p> Fri, 04 Dec 2009 00:53:07 +0000 linkding-ssg:bookmark:12659 algorithms databases geo hilbertcurves indexing quadtrees spatial http://svay.com/blog/index/post/2009/06/19/Face-detection-in-pure-PHP-(without-OpenCV) Surprised the code is so short. "Lately, I've been looking for ways to detect faces in photos with PHP. Nowadays, face detection is built in many consumer products (camera obviously, but also Google and iPhoto), and seems to be a pretty common job. So I expected to find many solutions for doing it with PHP. Surprisingly, the only one I could find is OpenCV, an opensource lib that was originally developed by Intel. OpenCV seems to perform well but you need to be able to install it on your server. In my case, I wanted to have a pure PHP solution, so it can work with most hosts."<br/> <p><strong>Tags:</strong> #algorithms #facedetection #photography #php #webdev</p> Thu, 25 Jun 2009 15:29:52 +0000 linkding-ssg:bookmark:12368 algorithms facedetection photography php webdev http://alteredqualia.com/visualization/evolve <p><strong>Tags:</strong> #ai #algorithms #evolution #genetics #graphics #javascript #science</p> Thu, 11 Dec 2008 02:56:11 +0000 linkding-ssg:bookmark:11764 ai algorithms evolution genetics graphics javascript science http://www.joelonsoftware.com/items/2006/08/01.html "I hope you're convinced, by now, that programming languages with first-class functions let you find more opportunities for abstraction, which means your code is smaller, tighter, more reusable, and more scalable."<br/> <p><strong>Tags:</strong> #abstraction #algorithms #functions #google #languages #mapreduce #microsoft #programming</p> Sat, 22 Nov 2008 01:28:23 +0000 linkding-ssg:bookmark:11695 abstraction algorithms functions google languages mapreduce microsoft programming http://www.youtube.com/watch?v=vIFCV2spKtg Almost kind of creep - an image resize algorithm that calculates least-important seams in an image to remove as it's resized / scaled.<br/> <p><strong>Tags:</strong> #algorithms #editing #images #nifty #photos #photoshop</p> Wed, 22 Aug 2007 15:13:31 +0000 linkding-ssg:bookmark:9527 algorithms editing images nifty photos photoshop http://www.youtube.com/watch?v=qDSGmx8c2AM "From Dattebayo's fansub release of Pythagoras Switch.
