Two new methods are presented for recovering the focused image of an object from only two
blurred images recorded with different camera parameter settings. The camera parameters …

A new shape-from-focus method is described which is based on a new concept, named
focused image surface (FIS). FIS of an object is defined as the surface formed by the set of …

We describe a method for modeling the dynamic behavior of splashing fluids. The model
simulates the behavior of a fluid when objects impact or float on its surface. The forces …

A passive AF algorithm for the digital still camera is proposed. As a class of hybrid
processing techniques, the proposed algorithm utilizes the two different focus measures by …

A new technique is presented which allows the use of a front‐end sensor head for in situ
and on‐line characterization of cell concentration and cell size during fermentation. An …

This paper compares the performances of the binocular cues of stereo and vergence, and
the monocular cue of focus for range estimation using an active vision system. The …

An optimization approach to automatic sensor and light source positioning for a machine
vision task, where geometric measurement and/or object verification is important, is …

This paper presents a structure adaptive anisotropic filtering method and its applications. It
differs from other techniques in that instead of using local gradient as a means of controlling …

A novel approach to constant-magni cation imaging is proposed. Magni cation variations
due to changes in focus setting pose problems for important vision techniques, such as …

A new method for actively recovering depth information using image defocus is
demonstrated and shown to support active stereo vision depth recovery by providing …
