An image matching demo that uses OpenCV SURF (Speeded Up Robust Features) descriptors. It finds matching points between two images. Images can be selected from phone’s gallery.The find_obj.cpp demo in OpenCV samples is slightly modified and used. Image matching of default images took 5.162 sec on my Samsung Galaxy S phone.*Previous changesv1.1-App name from SURF to SURF Image Matching.v1.2-Default images from Valkyrie to Dora. Cuter!-Internal processing image size: maximum height (or width) is changed to 320pixel internally to reduce processing time.Matching quality will be degraded but much faster than before. v1.3-Memory leaking problem solved.-Preventing selection of images larger than 3.2M pixels.v1.4-About dialogv1.5-png file support-Youtube instruction is added to about dialog v1.6-Google Analytics added-Blog link modified-System exit method cahngedv1.7-Google Analytics removedv1.8-Proguard-Blog link
