Extended Depth of Field
I n t roduc t ion The narrow depth of field of the light microscope is either an asset or a liability depend microscopist. Occasionally, by limiting the image to a narrow plane in the vertical axis, i observer’s attention by isolating structures in a thick sample, perm object while ignoring distracting elements abov cases, this feature is a liability when the object’s importance lies in its thr...
متن کاملCompressive extended depth of field using image space coding
We present a prototype imaging system that utilizes focal and temporal image space modulation to compress high-frequency, volumetric spatiotemporal information into low-framerate, planar images. 24-frame video sequences and extended depth of field reconstructions from single compressive measurements are reported. OCIS codes: (110.1120) Apertures; (110.1758) Computational imaging
متن کاملExtended Depth of Field for Fluorescence Microscopy
High numerical aperture objectives result in extremely shallow depths of field, which may or may not be desired by the user of the microscope. When looking at extended objects, planes that arent necessarily perpendicular to the light path, or fluorophores that move in and out of focus, an extended depth of field (EDOF) would be useful to fully visualize the sample. PSF engineering can be applie...
متن کاملDepth-of-Field Rendering by Pyramidal Image Processing
We present an image-based algorithm for interactive rendering depth-of-field effects in images with depth maps. While previously published methods for interactive depth-of-field rendering suffer from various rendering artifacts such as color bleeding and sharpened or darkened silhouettes, our algorithm achieves a significantly improved image quality by employing recently proposed GPU-based pyra...
متن کاملBipolar Incoherent Image Processing for Edge Detection of Medical Images
This paper proposed a novel algorithm to detect the contour map of tumor using bipolar incoherent image processing method. If the edges, size and location of the abnormality were detected, it would be useful in diagnosing the disease. Technique for edge detection using an acousto optic two-pupil heterodyne scanning system was proposed. Boundary extraction was discussed based on edge detection b...
