   University essay from Lunds universitet/Avdelningen för Energi och byggnadsdesign

   Author : Erik Hjorth; Florian Wochele; [2017]
   Keywords : Technology and Engineering;

   Abstract : With an increasing usage of photovoltaic panels also in urban context the cases of glare caused by photovoltaic systems are raising. Many countries have low or no regulations regarding outdoor glare caused by daylight, therefore legal cases can be complicated. READ MORE

3. 17. Contrast Enhancement of Colour Images using Transform Based Gamma Correction and Histogram Equalization

   University essay from Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

   Author : Pruthvi Venkatesh Gatti; Krishna Teja Velugubantla; [2017]
   Keywords : Contrast Enhancement; Image Processing; Traditional Histogram Equalization; Transformed Based Gamma Correction.;

   Abstract : Contrast is an important factor in any subjective evaluation of image quality. It is the difference in visual properties that makes an object distinguishable from other objects and background. Contrast Enhancement method is mainly used to enhance the contrast in the image by using its Histogram. READ MORE

6. 20. Assessment of Daylighting and Electric Lighting Performance in a Retrofitting Project: A Case Study in Sweden

   University essay from Lunds universitet/Avdelningen för Energi och byggnadsdesign

   Author : Xueting Wang; [2017]
   Keywords : Daylighting Assessment; Electric Lighting Assessment; Field Measurement; Lighting Simulation; Daylight Factor; Daylight Glare Probability; Technology and Engineering;

   Abstract : Newly constructed building stocks have been decreasing in last decades; thus, renovation and retrofitting represent a large amount of opportunities to upgrade the building performance and energy efficiency of building assets in their life span, as well as to reduce greenhouse gas emissions. An overall assessment of a lighting retrofit project can support to judge the quality of a retrofit as good or bad and evaluate the application of a retrofit measure in practice, as well as provide quantitatively based cases for future implementations.
