Content and Style Aware Generation of Text-Line Images for Handwriting Recognition.
IEEE Trans Pattern Anal Mach Intell

Article Synopsis
- Handwritten Text Recognition shows strong results in benchmarks but requires large labeled training datasets due to the variety in handwriting styles.
- To reduce the need for extensive manual labeling, synthetic data from TrueType fonts is often used, although it introduces a style bias that affects recognition accuracy.
- To overcome this, a new generative method is introduced that creates diverse handwritten text images based on visual appearance and text content, which has been shown to significantly enhance recognition performance through experimental validation.
A simple and effective method to introduce precise amounts of doping in nanomaterials produced from the bottom-up assembly of colloidal nanoparticles (NPs) is described. The procedure takes advantage of a ligand displacement step to incorporate controlled concentrations of halide ions while removing carboxylic acids from the NP surface. Upon consolidation of the NPs into dense pellets, halide ions diffuse within the crystal structure, doping the anion sublattice and achieving n-type electrical doping.
