Long-term Depression01:05

Long-term Depression

33.2K
Long-term depression, or LTD, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in the brain. LTD is the process of synaptic weakening that occurs over time between pre and postsynaptic neuronal connections. The synaptic weakening of LTD works in opposition to synaptic strengthening by long-term potentiation (LTP) and together are the main mechanisms that underlie learning and memory.

Directional Terms

16.0K
Directional terms are essential for describing the relative locations of different body structures. For instance, an anatomist might describe one band of tissue as "inferior to" another, or a physician might describe a tumor as "superficial to" a deeper body structure. These terms often use comparative terms in pairs to trace out the relative locations of one body part to another or descriptions of body tissues like the deeper ones from superficially present with reference to...

Long-Term Memory01:18

Long-Term Memory

659
Long-term memory is a relatively permanent type of memory, capable of storing vast amounts of information over extended periods. Its storage capacity is generally considered unlimited.
Long-term memory can be categorized into two primary types: explicit and implicit memory. Explicit memory, also known as declarative memory, involves the conscious recollection of information that we deliberately try to remember, recall, and articulate. This type of memory encompasses specific facts, events, and...

    Area of Science:

    • Computer Vision
    • Artificial Intelligence

    Background:

    • Conventional video saliency detection methods often fail with transient issues due to limited temporal information.

    Main Methods:

    • Utilizing supervised deep convolutional neural networks (CNNs).
    • Identifying 'beyond-scope' frames with robust long-term saliency clues.
    • Aligning identified long-term clues with the current frame for enhanced detection.

    Main Results:

    • Improved performance in video saliency detection compared to conventional methods.
    • Enhanced robustness against transient failure cases in video analysis.

    Conclusions:

    • Supervised deep CNNs effectively utilize long-term spatial-temporal information for superior video saliency detection.
    • The proposed method offers a more reliable approach to video saliency detection by incorporating broader temporal context.
