this study presents the natural dye recovery from various biodegradable temple and household wastes. the raw material for colour extraction consisted residual flowers and garlands from various temples as well as onion and vegetables peels from vegetable markets, university hostels, and households, which were washed, dried, crushed, and sieved. the extracted natural colours were produced by mean...

Image synthesis based on natural language description has become a research hotspot in edge computing artificial intelligence. With the help of generative adversarial networks, field made great strides high-resolution image synthesis. However, there are still some defects authenticity synthetic single-target images. For example, will be abnormal situations such as “multiple heads” and mouths” w...

In everyday scenes, the effective light (the actual in a space) can be defined as complex field, resulting from mixture of emissive sources and indirect mutual surface (inter-)reflections. Hence, field typically consists diffuse directional illumination varies spectral irradiance function location direction. The spatially varying differences between spectra induce correlated colour temperature ...

The paramer mismatch-based spectral gamut mapping framework is an approach which optimizes the spectral reproduction colorimetrically for multiple viewing conditions. Unfortunately, due to the pixelwise nature of this method, almost similar neighboring pixels might be mapped to completely different colorants which yield disturbing banding artifacts. The previous proposed solution for this probl...
