Depth Perception and Spatial Vision

Depth Perception and Spatial Vision

Depth perception is the ability to perceive objects three-dimensionally. It relies on two types of cues: binocular and monocular. Binocular cues depend on the combination of images from both eyes and how the eyes work together. Since the eyes are in slightly different positions, each eye captures a slightly different image. This disparity between images, known as binocular disparity, helps the brain interpret depth. When the brain compares these images, it determines the distance to an object.

Area of Science:

Computer Science
Human-Computer Interaction
Signal Processing

Background:

Wireless 3D video transmission faces challenges like limited bandwidth and channel impairments, leading to packet loss.
Packet loss in stereoscopic 3D (S3D) video can cause binocular rivalry, a phenomenon resulting in visual discomfort and reduced quality of experience (QoE).
Understanding and mitigating binocular rivalry is crucial for improving S3D video delivery.

Purpose of the Study:

To analyze the impact of binocular rivalry on macroblock (MB) losses and error propagation in S3D video transmission systems.
To evaluate existing error concealment techniques for contiguous lost MBs under various transmission impairments.
To enhance the overall viewer's QoE by minimizing binocular rivalry effects in S3D video.

Main Methods:

Utilized Joint Test Model (JM) reference software, recommended by the International Telecommunication Union (ITU), for simulating S3D video processing.
Applied existing error concealment techniques to contiguous lost macroblocks (MBs) resulting from simulated packet loss.
Conducted objective evaluations to validate the simulated packet loss environment and subjective testing with human subjects to assess QoE.

Main Results:

Quantified the impact of binocular rivalry on MB losses and error propagation in S3D video transmission.
Demonstrated the effectiveness of error concealment techniques in mitigating visual discomfort caused by packet loss.
Statistically compared the effects of binocular rivalry versus non-rivalry error conditions using Student's t-test.

Conclusions:

Binocular rivalry significantly impacts the QoE of S3D video, causing visual discomfort and affecting perceived video quality.
Error concealment strategies can effectively reduce the negative consequences of packet loss and binocular rivalry.
Minimizing binocular rivalry is essential for achieving error-free 3D video communication and enhancing viewer satisfaction.
