Automatic Digital Image Stabilization
نویسندگان
چکیده
This paper presents an automatic digital image stabilization system that is able to handle large image displacements. The system has been implemented in a parallel pipeline image processing hardware (Datacube Max Video 200) connected to a SUN SPARCstation 20/612 via a VME bus adaptor. Our technique is based on a two-dimensional feature-based multi-resolution motion estimation algorithm, that tracks a small set of features to estimate the motion of the camera. Stabilization is achieved by combining all motion from a reference frame and subtracting this motion from the current frame. Preliminary experimental results using video sequences taken from a camera rigidly mounted on a vehicle moving on rough terrain demonstrate the robustness of the system when processing 15 frames per second.

Fuzzy Neighbor Voting for Automatic Image Annotation
With quick development of digital images and the availability of imaging tools, massive amounts of images are created. Therefore, efficient management and suitable retrieval, especially by computers, is one of themost challenging fields in image processing. Automatic image annotation (AIA) or refers to attaching words, keywords or comments to an image or to a selected part of it. In this paper,...
متن کاملAutomatic Detection and Localization of Surface Cracks in Continuously Cast Hot Steel Slabs Using Digital Image Analysis Techniques
Quality inspection is an indispensable part of modern industrial manufacturing. Steel as a major industry requires constant surveillance and supervision through its various stages of production. Continuous casting is a critical step in the steel manufacturing process in which molten steel is solidified into a semi-finished product called slab. Once the slab is released from the casting unit, th...
متن کاملProcessing Digital Image for Measurement of Crack Dimensions in Concrete
The elements of the concrete structure are most frequently affected by cracking. Crack detection is essential to ensure safety and performance during its service life. Cracks do not have a regular shape, in order to achieve the exact dimensions of the crack; the general mathematical formulae are by no means applicable. The authors have proposed a new method which aims to measure the crack dimen...
متن کاملImage quality enhancement in digital panoramic radiograph
One of the most common positioning errors in panoramic radiography is palatoglossal air space above the apices of the root of maxillary teeth. It causes a radiolucency obscuring the apices of maxillary teeth. In the case of this positioning error, the imaging should be repeated. This causes the patient be exposed to radiation again. To avoid the repetition of exposing harmful X-rays to the pati...
متن کاملAutomatic Restoration Algorithms for 35mm film
Classical film restoration is based on special copying machines to improve the quality of safekeeping copies. Only a small class of defects can be removed by such a process, because the unit of manipulation is always the physical film strip. With help of digital image processing techniques the restoration process can be adapted for each frame or even pixel and also for many kinds of defects. Th...
