Light Acquisition02:16

Light Acquisition

8.6K
In order to produce glucose, plants need to capture sufficient light energy. Many modern plants have evolved leaves specialized for light acquisition. Leaves can be only millimeters in width or tens of meters wide, depending on the environment. Due to competition for sunlight, evolution has driven the evolution of increasingly larger leaves and taller plants, to avoid shading by their neighbors with contaminant elaboration of root architecture and mechanisms to transport water and nutrients.

Reducing Line Loss

196
In a three-phase circuit, line loss is an indicator of energy dissipated as heat due to the resistance of transmission lines. To address this, incorporating transformers into the system—a step-up transformer at the source and a step-down transformer at the load—is a strategic solution. Two three-phase transformers are introduced to improve this.
With a step-up transformer at the source, the voltage is increased, thereby reducing the current in the transmission lines since power loss...

    Main Methods:

    • SRENet employs a two-step strategy involving foreground-background separation and saliency extraction.
    • Local illumination enhancement is applied to salient regions to improve object exposure.
    • A fusion module integrates local enhancements with global lighting optimization.

    Main Results:

    • SRENet demonstrates superior lighting enhancement for local illumination compared to existing methods.
    • The network effectively preserves globally optimal lighting results.
    • Experimental results show improved performance in various exposure correction and lighting quality tasks.

    Conclusions:

    • SRENet offers a balanced approach to lighting enhancement by considering both global and local image properties.
    • The saliency-guided, two-step strategy effectively enhances exposure quality for important image regions.
    • The proposed method provides a significant advancement in low-level image processing for lighting correction.
