Optics Express, 2020 Single-photon lidar (SPL) is a promising technology for depth measurement at long range or from weak reflectors because of the sensitivity to extremely low light levels. However, constraints on the timing resolution of existing arrays of single-photon avalanche diode (SPAD) detectors limit the precision of resulting depth estimates.

A depth image restoration algorithm based on WMF-ACA
上海师范大学学报. 自然科学版, 2021 To solve the problem of holes and noise in the depth image due to the limitation of RGBD camera hardware, a color imageguided method for filling holes in depth image was proposed. Firstly, for the boundary area of the depth image, a weighted mode filter (

Exploring depth information for head detection with depth images [PDF]
2016 13th IEEE International Conference on Advanced Video and Signal Based Surveillance (AVSS), 2016 Head detection may be more demanding than face recognition and pedestrian detection in the scenarios where a face turns away or body parts are occluded in the view of a sensor, but locating people is needed. In this paper, we introduce an efficient head detection approach for single depth images at low computational expense.

Exemplar-based image completion using image depth information. [PDF]
PLoS ONE, 2018 Image completion techniques are required to complete missing regions in digital images. A key challenge for image completion is keeping consistency of image structures without ambiguity and visual artifacts. We propose a novel method for image completion

Mackerel Fat Content Estimation Using RGB and Depth Images
IEEE Access, 2021 We propose a method for estimating the fat content of mackerels from their images. The market value of fish varies greatly depending on the fat content.
