    Types of Global Positioning System Surveys

    GPS surveying methods vary in application, accuracy, and data collection techniques, catering to diverse surveying and mapping needs. Static GPS, kinematic GPS, and real-time kinematic (RTK) surveying are widely used. Each technique offers distinct advantages.Static GPS involves placing one receiver at a known reference point and another at the target point. It collects exact positional data by observing multiple satellite ranges over an extended period, achieving centimeter-level accuracy for...

    This study introduces a new deep metric learning approach for remote sensing object retrieval. The generalized likelihood ratio test-based deep metric learning (GLRT-DML) method improves accuracy by considering feature distribution, outperforming existing techniques.

    Area of Science:

    • Computer Science
    • Remote Sensing
    • Machine Learning

    Background:

    • Remote sensing object retrieval (RSOR) faces challenges with traditional distance metrics that are sensitive to noise and variations.
    • Existing methods often fail to account for feature distribution, leading to suboptimal performance in identifying objects in large image databases.

    Purpose of the Study:

    • To develop a novel, distribution-aware metric learning framework for enhanced remote sensing object retrieval.
    • To address the limitations of distribution-agnostic metrics in RSOR by incorporating feature distribution information.

    Main Methods:

    • Proposed a generalized likelihood ratio test-based deep metric learning (GLRT-DML) approach inspired by the Neyman-Pearson theorem.
    • Leveraged distribution information from feature embeddings to create a robust metric space for RSOR.
