Automatic Measurement of Multi-Posture Beef Cattle Body Size Based on Depth Image

open access: yes智慧农业, 2022
Beef cattle in the farm are active, which leads the collection of posture of the beef cattle changeable, so it is difficult to automatically measure the body size of the beef cattle.

Mackerel Fat Content Estimation Using RGB and Depth Images

open access: yesIEEE 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.

Approximate Depth Shape Reconstruction for RGB-D Images Captured from HMDs for Mixed Reality Applications

open access: yesJournal of Imaging, 2020
Depth sensors are important in several fields to recognize real space. However, there are cases where most depth values in a depth image captured by a sensor are constrained because the depths of distal objects are not always captured.

Feature Pyramid Network Based Efficient Normal Estimation and Filtering for Time-of-Flight Depth Cameras

open access: yesSensors, 2021
In this paper, an efficient normal estimation and filtering method for depth images acquired by Time-of-Flight (ToF) cameras is proposed. The method is based on a common feature pyramid networks (FPN) architecture.

A Fractional-Order Total Variation Regularization-Based Method for Recovering Geiger-Mode Avalanche Photodiode Light Detection and Ranging Depth Images

open access: yesFractal and Fractional, 2023
High-quality image restoration is typically challenging due to low signal–to–background ratios (SBRs) and limited statistics frames. To address these challenges, this paper devised a method based on fractional-order total variation (FOTV) regularization ...

Depth perception with gaze-contingent depth of field [PDF]

open access: yes, 2014
Blur in images can create the sensation of depth because it emulates an optical property of the eye; namely, the limited depth of field created by the eye's lens. When the human eye looks at an object, this object appears sharp on the retina, but objects

A Fast Single Image Haze Removal Algorithm Using Color Attenuation Prior [PDF]

open access: yes, 2015
Single image haze removal has been a challenging problem due to its ill-posed nature. In this paper, we propose a simple but powerful color attenuation prior for haze removal from a single input hazy image.
