An Efficient Neural Network for Shape from Focus with Weight Passing Method
Applied Sciences, 2018 In this paper, we suggest an efficient neural network model for shape from focus along with weight passing (WP) method. The neural network model is simplified by reducing the input data dimensions and eliminating the redundancies in the conventional ...

3D Measurement Method for Saturated Highlight Characteristics on Surface of Fuel Nozzle
Sensors, 2022 Saturated highlights on metal surfaces reduce the detection accuracy of fuel nozzles. In this paper, we propose an image inpainting method with a saturated highlight based on the statistics of similar patches used in prior segmentation of the subregion ...

Sampling Based on Kalman Filter for Shape from Focus in the Presence of Noise
Applied Sciences, 2019 Recovering three-dimensional (3D) shape of an object from two-dimensional (2D) information is one of the major domains of computer vision applications. Shape from Focus (SFF) is a passive optical technique that reconstructs 3D shape of an object using 2D

Deep Eyes: Binocular Depth-from-Focus on Focal Stack Pairs
, 2020 Human visual system relies on both binocular stereo cues and monocular focusness cues to gain effective 3D perception. In computer vision, the two problems are traditionally solved in separate tracks.

Rational-operator-based depth-from-defocus approach to scene reconstruction [PDF]
, 2013 This paper presents a rational-operator-based approach to depth from defocus (DfD) for the reconstruction of three-dimensional scenes from two-dimensional images, which enables fast DfD computation that is independent of scene textures.

Variational Uncalibrated Photometric Stereo under General Lighting [PDF]
, 2019 Photometric stereo (PS) techniques nowadays remain constrained to an ideal laboratory setup where modeling and calibration of lighting is amenable. To eliminate such restrictions, we propose an efficient principled variational approach to uncalibrated PS
