A local adaptive method is proposed for automatic detection of microaneurysms in a digital ocular fundus image. Multiple subregions of the image are automatically analyzed and adapted to local intensity variation and properties. A priori region and location information about structural features such as vessels, optic disk and hard exudates are incorporated to further improve the detection accuracy. The method effectively improves the specificity of microaneurysms detection, without sacrificing sensitivity. The method may be used in automatic level-one grading of diabetic retinopathy screening.

Method and system for local adaptive detection of microaneurysms in digital fundus images

A hybrid digital watermarking system for video authentication includes an authenticated acquisition subsystem for digitally watermarking video data and a video management subsystem in signal communication with the authenticated acquisition subsystem for verifying the digitally watermarked video data, where the authenticated acquisition subsystem may include a watermarking device for applying each of an identity signature and a control signature to the video data within a hybrid digital watermark, and the hybrid digital watermark may achieve progressively varying robustness by means of error-correcting signature coding and/or rate-distortion guided bit embedding.
