Example: Using Core Image Face Detection On A Live Video Feed
Some time ago I posted a tutorial on the basics of using Core Image face detection on the iOS platform.
Something that was asked in the comments thread for that post was how to use Core Image face detection on a live video feed – and whether it was fast enough.
Recently I received a submission from Jeroen Trappers showing how to use Core Image face detection on a live video feed, and place a moustache on the faces found within the video stream.
Easy And Extremely Fast iOS UIImage Image Processing Library (Blur/Sharpen/Emboss)
With this Objective-C library for image filters based on Filterr.js and Core Image in iOS 5 there are a number of ways to easily process images. There are times however when you might need a bit more speed and don’t want to try rolling your own filter.
Today I came across an image processing library that is designed for speed and provides that enhanced speed by using Apple’s vDSP API. The library provides UIImage categories and provides allows you to easily apply sharpen, blur (box, gaussian and motion), and emboss filters.
App Review Sites Listing Adds 50+ Sites – Traffic Rankings Updated
Not too long ago I shared news about a great template to help get reviewers to look at your app. About 3 years ago now I first added a listing of iPhone app review sites.
The iOS app review site list has once again been updated to 167 sites after many hours (and some help) and ranked by traffic.
A few people asked if there was a PDF available – I’m working on it, and should be out either later tonight or tomorrow.
Open Source iOS Library For Highly Customizable Animated Semi-Modal Views
In the past I’ve mentioned a great library that can be used to create elegant popup style modal panels.
Recently I received the submission of an interesting component that allows you to create partial modal views that cover the bottom of the screen and is styled after the National Geographic parks guide app.
Open source: Library For Easy Clear App Style (And More) Folding Transitions Between UIViews
Fold transitions were made famous by the popular Clear app, and previously I posted a gesture responsive UITableView with fold transitions.
Today I came across another library specifically for creating fold transitions. Using this library you can create a number of different fold transitions.
