摘要： A method for authenticating security markers includes capturing an image of a region of interest on a product with a camera; storing image data in a two-dimensional array on a microprocessor; counting a number of pixels at or above a predetermined brightness level in the image data with the microprocessor to determine a first score; establishing an area within the image; counting a number of pixels within the area to determine a second score; calculating a ratio of the second score to the first score; and if the ratio is above a predetermined threshold the security marker is authenticated.

摘要： A method for detecting authorized security markers includes capturing an image of a region of interest on a product with a camera; storing image data in a two-dimensional array on a microprocessor; counting a number of pixels at or above a predetermined brightness level in the image data with the microprocessor to determine a first score; eroding the image data; counting the pixels which remain at or above the predetermined brightness level after erosion to determine a second score; calculating a ratio of the second score to the first score; and producing a first authentication signal if the ratio meets a first predetermined criteria.

摘要： A method for displaying live video of a tooth identifies a tooth tissue region in a viewable image frame obtained from a video stream and processes pixel data within the tooth tissue region to identify a suspected caries site. Intensity values for pixels that correspond to the suspected caries site are modified and a highlighted viewable image frame is formed as a combination of the modified intensity values corresponding to the suspected caries site and other pixel values in the viewable image frame. The highlighted viewable image frame is displayed in video form.
