InternetHDR: Enhancing an LDR image using visually similar Internet images

Traditionally, High Dynamic Range (HDR) images are created by combining photographs taken at different exposure times. This technique has the overhead to capture more than single image of the scene while changing the exposure value. The proposed approach, InternetHDR, aims at creating an HDR image without the need of explicitly taking differently exposed images. This novel approach uses a single Low Dynamic Range (LDR) image as input to create an HDR image by combining information from visually similar images mined from the internet sites using Google image search. The results show that visually pleasing HDR images can be created using a single LDR image and additional information from the visually similar images mined from the internet.
