Abstract
A system, method and a computer program product for handling text distracters in a visual search have been disclosed. The system considers an image captured on a handheld device, as a query image and subsequently identifies the textual portions of the query image. The textual portions of the query image are smoothened in order to reduce the keypoints present in the textual portions. Non-textual portions in proximity to the textual portions are also selectively smoothened in order to prevent formation of an artificial border between the textual portions and non-textual portions. Further, the features are extracted from the non-textual portions of the query image are compared with the features of the images stored in a repository. An image whose features match with the extracted features is identified as an image relevant to the query image, and the identified image is transmitted, along with the associated metadata to the handheld device for display.
