Implemented FaceThumbnailCropper and UIImageRotationFixer that serve as helper classes for ReKognitionSDK.
FaceThumbnailCropper crops face thumbnails out of the raw image, merges thumbnails into a single compressed image, and serves that image as the source for ReKognition API.
UIImageRotationFixer rotates the underlining CGImageRef of an UIImage to its up un-mirrored position. It is used to correct the source images whose orientation is other than upwards, like images taken from camera roll.

ReKognitionResults provides data classes and parsing methods for ReKognition API response.
This ReKognition iOS SDK is intent for developers who want to integrate ReKognition API into their iOS applications. The folder contains our ReKognition iOS SDKs (ReKognitionSDK.h and ReKognitionSDK.m under folder named SDK) and a simple example to demo the SDK. For more information about our ReKognition API, please read our documentation.

Use your own API Key and Secret in RekognitionSDK.
static NSString *API_Key = @"YOUR_API_KEY";
static NSString *API_Secret = @"YOUR_API_SECRET";This demo app allows you to perform the following tasks:
-
Select a photo from the album or take a picture using the camera;
-
Recognize the image using the our face detection and scene understanding functions;
Notes: the demo app shows the proper usage of FaceThumbnailCropper and UIImageRotationFixer helper classes.
