Descrizione Color Interpolation Techniques
This book investigates the recent automated greyscale image colorization techniques using a custom developed GNU Image Manipulation Package (GIMP) plug-in. This process involves the transfer of color between a compositionally similar source color image and destination greyscale image. Emerging colorization techniques offer an automated solution to the colorization problem. A GIMP plug-in was implemented, that GIMP plug-in was used to critically evaluate the colorization process. A complete analysis was performed on the images by varying parameters to find the best balance between the neighbourhood size, sampling technique, weighted ratios of pixel luminance, standard deviation and mean. The plug-in developed offers an integrated greyscale image colorization capability to the GIMP suite, and brings the power of automated colorization to the GIMP user community.It was discovered that a trivial scan line uniform sampling technique produced comparable if not slightly better results than more computationally expensive techniques based on pixel neighbourhood statistical analysis. This book shows that it is important for images to correlate in composition and size.
