摘要： A method is disclosed for processing of images to detect dental caries, that includes the following steps. Directing incident light (16) toward a tooth (20), where this light excites a fluorescent emission from the tooth. Obtaining a fluorescence image (35) from the fluorescent light component (19), and obtaining a reflectance image (34) from the back-scattered light (18) from the tooth. Applying a color balance operation to the reflectance image. Removing the specular reflectance components from the color balanced reflectance image (82) to give a back-scattered reflectance image (50). Registering the fluorescent image with the back-scattered reflectance image. Combining the registered fluorescent image (115) with the back-scattered reflectance image to provide a diagnostic image (52).

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.

摘要： A method for suppressing noise in a diagnostic 3-D image, executed at least in part on a logic processor, captures, at each of a number of projection angles, 2-D image projection data, wherein each 2-D image projection has a central pixel and arranges the 2-D image projection data to form a 3-D data set. Each of the 2-D image projections is processed by performing a diffusion filtering process that obtains a homogeneity value for the 3-D data set, generates a diffusion conductance function according to an intensity gradient between adjacent digital image elements, and applies the diffusion filtering process to digital image elements according to the obtained homogeneity value, the generated diffusion conductance function, and a weighting value that relates to the distance of each pixel in the projection from the central pixel. The diagnostic 3-D image is reconstructed from the processed 2-D image projections.

摘要： A method for adjusting dot-gain for a halftone binary bitmap file comprises inputting a halftone binary bitmap file consisting of binary pixels (400) to an asymmetric digital filter (500). The binary pixels are filtered with the asymmetric digital filter and generates multi-level pixels (506). The multi-level pixel are compared to a preset level (408) and generates a binary pixel output (410). The binary pixel output is collected and forms an adjusted halftone binary bitmap file (270).

摘要： A method of reducing artifacts in a digital radiographic image identifies either a row or column direction for the artifacts in the image data as a predominant direction and obtains a measurement of the image data frequency content that is subject to artifacts from the image content according to the predominant direction. The measurement of image data frequency content subject to the artifacts is tested according to a predetermined threshold. Artifacts are reduced when the predetermined threshold is exceeded by generating one or more suppression factors according to the testing results, decomposing the image content into at least two frequency bands in each row and column direction, applying the one or more suppression factors to modify at least one of the frequency bands, and recomposing the image content by recombining the at least one modified frequency band with one or more other bands into which the image had been decomposed.
