Vision01:24

Vision

61.6K
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.

Archival Research01:40

Archival Research

17.6K
Some researchers gain access to large amounts of data without interacting with a single research participant. Instead, they use existing records to answer various research questions. This type of research approach is known as archival research. Archival research relies on looking at past records or data sets to look for interesting patterns or relationships. For example, a researcher might access the academic records of all individuals who enrolled in college within the past ten years and...

ER Retrieval Pathway01:45

ER Retrieval Pathway

5.0K
In the secretory pathway, vesicles transport proteins from one cellular compartment to another in forward transport to deliver the protein to its correct location. Occasionally, misfolded proteins and incorrect proteins escape their original compartments, and a retrieval pathway is used to return the escaped proteins to their original compartment.
The ER uses many checkpoints to prevent the entry of incorrectly folded or a resident protein as cargo onto a transport vesicle. These mechanisms...

Visual System01:26

Visual System

2.3K
Light enters the eye through the cornea, a transparent, dome-shaped surface covering the surface of the eyeball that helps to direct and focus incoming light. This light is then channeled toward the pupil, an adjustable opening whose size is controlled by the iris. The iris, a pigmented muscle, regulates the amount of light entering the eye by contracting or dilating the pupil, thereby ensuring optimal light levels for clear vision.
Once through the pupil, the light passes through the lens, a...

    Area of Science:

    • Computer Science
    • Information Retrieval
    • Web Search Technology

    Background:

    • Traditional search engines rely solely on text for document relevance.
    • Image content within web pages is largely ignored by current search algorithms.
    • This limits the semantic understanding and retrieval accuracy of search engines.

    Purpose of the Study:

    • To investigate the potential of using image content to improve web document retrieval.
    • To develop and evaluate a system that integrates visual information into keyword-based search.
    • To enhance the semantic description of HTML documents for better search performance.

    Main Methods:

    • A web-scalable system was developed, initially using a text-based search engine for candidate retrieval.
    • Candidate documents were reranked using visual information extracted from page images.
    • The approach was tested on the TREC Million Query Track benchmark and validated using Amazon Mechanical Turk for relevance judgments.

    Main Results:

    • The integration of visual content led to improved accuracy for two distinct text-based search engines.
    • The system demonstrated enhanced performance compared to a pure text-based search approach.
    • Accuracy improvements were observed even for a top-performing text-based system.

    Conclusions:

    • Utilizing visual information from web page images effectively enriches document descriptions.
    • The proposed system offers a computationally efficient method to boost search engine performance.
    • Incorporating image-based reranking provides a significant accuracy improvement over text-only retrieval.
