2. 6. Pattern Recognition Methods for Oral Lesion Classification using Digital Color Images

   Author : Artur Chodorowski; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; oral lesions; supervised classification; pattern recognition; computer-aided diagnosis; support vector machines; color; cancer; shape;

   Abstract : The present thesis addresses the development and application of pattern recognition methods for classification of oral lesions using digital color images as input. The human oral cavity is a site of numerous diseases and two of the common and visually similar lesions are oral leukoplakia and oral lichenoid reactions. READ MORE

4. 7. Signaling for color change in melanophores : and a biosensor application

   Author : Annika M. Karlsson; Samuel Svensson; Margareta Wallin; Linköpings universitet; []
   Keywords : color change; melanophores; tyrosine; phosphorylations; melatonin; nitric oxide; MEDICINE; MEDICIN;

   Abstract : Melanophores are dark brown pigment cells located in the skin of fish, amphibia, reptiles, and many invertebrates. The color of the animal can change via rearrangement of pigment granules, melanosomes, in the cells. The dark melanophores can either hide colorful cells so that the animal appears dark, or let through colors from underneath. READ MORE

5. 8. Topics in color measurement

   Author : Lars Mattias Andersson; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Color characterizations of printing situations are essential for a correct color reproduction. To obtain a good color characterization, knowledge about the substrate, the printing process and the printer function are all of great importance. READ MORE

6. 9. Efficient Image Retrieval with Statistical Color Descriptors

   Author : Linh Viet Tran; Reiner Lenz; Björn Kruse; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; color properties; images; statistical; content-based image retrieval CBIR ; non-parametric density estimators; image database; Kernel; Gram-Schmidt; geometry-based; Information technology; Informationsteknologi;

   Abstract : Color has been widely used in content-based image retrieval (CBIR) applications. In such applications the color properties of an image are usually characterized by the probability distribution of the colors in the image. READ MORE

7. 10. Color Tuning for Perovskite Light-Emitting Diodes

   Author : Hongling Yu; Feng Gao; Xiaoke Liu; Olle Inganäs; Fengling Zhang; Maksym V. Kovalenko; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Perovskite light-emitting diodes; Color tuning; Pure and mixed halide; Spectral stability; White emission;

   Abstract : Metal halide perovskites (MHPs) are recognized as promising semiconductor materials for a variety of optical and electrical device applications due to their cost-effective and outstanding optoelectronic properties. As one of the most significant applications, perovskite light-emitting diodes (PeLEDs) hold promise for future lighting and display technologies, attributed to their high photoluminescence quantum yield (PLQY), high color purity, and tunable emission color.
