    Masking and Demasking Agents

    4.0K
    EDTA titrations may necessitate masking and demasking agents to temporarily protect a particular metal ion in a mixture from the EDTA reaction. These agents facilitate the sequential analysis of the metal ions by forming stable complexes with some—but not all—metal ions during certain steps.
    There are many masking agents, such as cyanide, fluoride, triethanolamine, thiourea, and 2,3-bis(sulfanyl)propan-1-ol (formerly 2,3-dimercapto-1-propanol), with the masking agent chosen based on...

    Absolute Motion Analysis- General Plane Motion

    706
    Visualize a drone, with its propellers spinning rapidly, hovering mid-air. The fascinating movements and operations of this drone can be comprehended by applying the principle of general plane motion.
    As the drone's propellers rotate, an upward force is generated that counteracts the force of gravity, enabling the drone to lift off from the ground. This initial movement of the drone is along a straight path, representing a form of translational motion. In this phase, every point on the...

    This study introduces a novel background-modeling-based adaptive prediction (BMAP) method for efficient surveillance video coding. BMAP doubles the compression ratio compared to AVC, enhancing both background and foreground prediction.

    Area of Science:

    • Computer Vision
    • Video Compression
    • Digital Signal Processing

    Background:

    • Exponential growth in surveillance video data necessitates advanced coding technologies.
    • Existing video coding standards are not optimized for surveillance video characteristics like static backgrounds.
    • Improved prediction efficiencies for background and foreground are crucial for surveillance video coding.

    Purpose of the Study:

    • To analyze and enhance background and foreground prediction efficiencies in surveillance video coding.
    • To propose a novel adaptive prediction method tailored for surveillance video characteristics.
    • To evaluate the performance of the proposed method against existing standards.

    Main Methods:

    • Developed a background-modeling-based adaptive prediction (BMAP) method.
