Depth Perception and Spatial Vision01:15

Depth Perception and Spatial Vision

2.7K
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.

Perception

1.8K
Perception is a fundamental psychological process that enables individuals to organize, interpret, and consciously experience sensory information. This process is crucial for understanding and interacting with the world around us. It includes both bottom-up and top-down processing, each playing a distinct role in how we perceive our environment.
Bottom-up processing begins at the sensory level, where receptors detect external environmental stimuli. These could include the tactile sensation of...

Perceptual Constancy

1.8K
Perceptual constancy is the ability to recognize that objects remain consistent and unchanged even when their appearance varies due to changes in sensory input. There are four main types of perceptual constancy: size constancy, shape constancy, color constancy, and brightness constancy.
Size constancy is the recognition that an object remains the same size, even when its image on the retina changes. For instance, a bus is perceived to be large enough to carry people, even if it looks tiny from...

Perception of Sound Waves01:01

Perception of Sound Waves

6.0K
The human ear is not equally sensitive to all frequencies in the audible range. It may perceive sound waves with the same pressure but different frequencies as having different loudness. Moreover, the perception of sound waves depends on the health of an individual's ears, which decays with age. The health of one's ears may also be affected by regular exposure to loud noises.
The pitch of a sound depends on the frequency and the pressure amplitude of the source. Two sounds of the same...

    Area of Science:

    • Computer Vision
    • Human-Computer Interaction
    • Image Processing

    Background:

    • Current stereo image quality assessment (SIQA) methods struggle with accurate modeling of binocular fusion and fine-grained perception.
    • Limitations exist in capturing the nuances of human visual system (HVS) processing for stereo images.

    Purpose of the Study:

    • To develop an advanced SIQA method that simulates key mechanisms of the HVS for more accurate quality prediction.
    • To overcome the limitations of existing SIQA models in binocular fusion and detailed perception.

    Main Methods:

    • A Perception-Inspired Network for SIQA was proposed, incorporating a difference-guided binocular fusion (DGBF) module.
    • A high-frequency enhancement module (HFEM) was developed to simulate HVS sensitivity to distortions in high-frequency components.
    • A hierarchical quality regression strategy was implemented to mimic human perception from local details to global judgment.

    Main Results:

    • The proposed method demonstrated superior performance compared to mainstream SIQA approaches.
    • Achieved a high Pearson Linear Correlation Coefficient (PLCC) of 0.9734 on the LIVE I database.
    • Achieved a PLCC of 0.9632 on the LIVE II database, indicating strong alignment with subjective evaluations.

    Conclusions:

    • The novel Perception-Inspired Network effectively simulates HVS mechanisms for improved SIQA.
    • The DGBF and HFEM modules, along with hierarchical regression, enhance the accuracy of stereo image quality prediction.
    • The proposed method offers a more reliable and human-aligned approach to assessing stereo image quality.
