Image Acquisition and Gradient Method for Main Subject Detection

Khushboo Pandey, Mr. Sanjeev Thakur

Abstract :

Image acquisition is the process of obtaining a digital image from a real world basis. Each step in the acquisition process may initiate casual changes into the values of pixels. These changes are called noise. The proposed algorithms do not depend on prior knowledge of the indoor/outdoor setting or scene, and are willing to software implementation on fixed–point programmable digital signal processors available in digital still cameras. In this paper, we join optical and digital image processing to execute the segmentation of the main subject without prior knowledge of the scene. In particular, we propose to get a picture in which the main subject is in center of attention, and the shutter aperture is fully open. The lens optics will blur any entity not in the plane of focus. For the acquired picture, this paper expands a computationally simple one–pass algorithm to segment the main subject. The Gradient information may be more consistent feature for segmentation.
