SIFTObjectDist

Finding distance between objects in images using SIFT

Code Structure

main.m               - the entry point of the program
sift.m               - script that involkes SIFT program based on various OS
SIFTmatch.m          - match SIFT descriptors according to the distance in Euclidean space
showkeys.m           - display SIFT descriptors
getPosition.m        - find the estimated position (x,y) for an object on a scene
objectScenesDistance - find the distance between the same object in two scenes
objectsDistance	     - find the distance between two objects in the same image

Sample Experiment Results

Distance between two objects in the same image

dist = objectsDistance('images/book1.jpg', 'images/book2.jpg', 'images/scene1.jpg');

📏 Result: approximately 592px.

Distance between the same object in different scenes

dist = objectScenesDistance('images/book1.jpg','images/scene1.jpg','images/scene2.jpg');

📏 Result: approximately 471px.
