    Base complementarity between the three base pairs of mRNA codon and the tRNA anticodon is not a failsafe mechanism. Inaccuracies can range from a single mismatch to no correct base pairing at all. The free energy difference between the correct and nearly correct base pairs can be as small as 3 kcal/ mol. With complementarity being the only proofreading step, the estimated error frequency would be one wrong amino acid in every 100 amino acids incorporated. However, error frequencies observed in...

    This study introduces LRANet++, an efficient end-to-end text spotting framework. It precisely detects arbitrary-shaped text using a novel low-rank approximation for shape representation and a triple assignment head for speed.

    Area of Science:

    • Computer Vision
    • Artificial Intelligence
    • Machine Learning

    Background:

    • End-to-end text spotting unifies text detection and recognition.
    • Current methods struggle with accurate and efficient arbitrary-shaped text spotting.
    • A key challenge is the lack of reliable and efficient text detection.

    Purpose of the Study:

    • To develop an accurate and efficient end-to-end text spotter for arbitrary-shaped text.
    • To address the bottleneck in text detection accuracy and efficiency.
    • To propose a novel parameterized text shape representation and a triple assignment detection head.

    Main Methods:

    • A novel parameterized text shape representation using low-rank approximation.
    • Exploiting shape correlations for a robust low-rank subspace construction.
