SIFT (Scale Invariant Feature Transform)
, 2016 Cap. 8, pp. 131-157 SIFT es un método que permite detectar puntos característicos en una imagen y luego describirlos mediante un histograma orientado de gradientes. Y además, lo hace de forma que la localización y la descripción presenta una gran invarianza a la orientación, la posición y la escala.

Electrochemical Modulation of Hole Extraction in NiO/Perovskite Bilayers
Advanced Materials Interfaces, EarlyView.The influence of hole depletion/accumulation on the hole extraction is evaluated in NiO/perovskite bilayers by transient spectroelectrochemical measurements. Metal‐halide perovskite thin films with different valence band positions are prepared, and the influence of band offset on the hole extraction kinetics is studied.

Improving the Photochemical Skeletal Enlargement of Pyridines to 1,2‐Diazepines with Isocyanates
Advanced Synthesis &Catalysis, Volume 367, Issue 5, March 4, 2025.Abstract In this work, we extend the one‐pot protocol to synthesize 1,2‐diazepines from commercially available and cheap starting materials. Capitalizing on isocyanate derivatives as activating agents, the photochemical skeletal enlargement occurs, while preserving key functional groups embedded in more than 30 substrates.
