Vision01:24

Vision

59.5K
Vision is the result of light being detected and transduced into neural signals by the retina of the eye. This information is then further analyzed and interpreted by the brain. First, light enters the front of the eye and is focused by the cornea and lens onto the retina—a thin sheet of neural tissue lining the back of the eye. Because of refraction through the convex lens of the eye, images are projected onto the retina upside-down and reversed.

Color Vision01:24

Color Vision

1.4K
Color perception begins in the retina, the light-sensitive layer at the back of the eye. Two main theories explain how colors are seen: the trichromatic theory and the opponent-process theory. The trichromatic theory, proposed by Thomas Young in 1802 and extended by Hermann von Helmholtz in 1852, suggests that color vision is based on three types of cone receptors in the retina. These cones are sensitive to different but overlapping ranges of wavelengths corresponding to red, blue, and green.

Depth Perception and Spatial Vision01:15

Depth Perception and Spatial Vision

1.9K
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.

Improving Translational Accuracy

14.1K
Base complementarity between the three base pairs of mRNA codon and the tRNA anticodon is not a failsafe mechanism. Inaccuracies can range from a single mismatch to no correct base pairing at all. The free energy difference between the correct and nearly correct base pairs can be as small as 3 kcal/ mol. With complementarity being the only proofreading step, the estimated error frequency would be one wrong amino acid in every 100 amino acids incorporated. However, error frequencies observed in...

Base Excision Repair01:54

Base Excision Repair

26.1K
One of the common DNA damages is the chemical alteration of single bases by alkylation, oxidation, or deamination. The altered bases cause mispairing and strand breakage during replication. This type of damage causes minimal change to the DNA double helix structure and can be repaired by the base excision repair (BER) pathways. BER corrects damaged DNA sequences by removing the damaged base and restoring the original base sequence using the complementary strand as a template.
The first step of...

Area of Science:

  • Robotics
  • Computer Vision
  • 3D Perception

Background:

  • Viewpoint Feature Histogram (VFH) is a standard for 3D object recognition and pose estimation.
  • VFH struggles with objects possessing mirrored structures, leading to ambiguous pose identification.
  • Accurate pose estimation is critical for robotic grasping operations.

Purpose of the Study:

  • To introduce a novel global point cloud descriptor, Orthogonal Viewpoint Feature Histogram (OVFH).
  • To enhance the reliability of object recognition and pose estimation, particularly for objects with mirrored symmetries.
  • To improve robot grasping success rates in complex scenarios.

Main Methods:

  • Developed OVFH by incorporating a surface shape component and an orthogonal viewpoint direction component.
  • Calculated the orthogonal viewpoint component using a reference frame estimated for the entire point cloud.
  • Integrated OVFH with the Iterative Closest Point (ICP) algorithm for precise pose registration.

Main Results:

  • OVFH demonstrates superior ability in distinguishing between mirrored poses compared to VFH.
  • Maintained robust object recognition performance while improving pose discrimination.
  • Experimental validation on a public dataset confirmed OVFH's effectiveness.

Conclusions:

  • The proposed OVFH descriptor significantly advances 3D object recognition and pose estimation for mirrored objects.
  • OVFH enables more reliable robot grasping, even for objects with symmetrical ambiguities.
  • This method offers a practical solution for real-world robotic applications requiring precise object manipulation.
