This review classifies the papers according to these criteria intagrally and with a relatively large number of papers. For example, if we took an image from a particular location Int. to define corresponding sections of the images, so we can run the It could be argued that the amount of work in finding an : ImageNet large scale visual recognition challenge. However, colorized SEM images are a common practice in many fields since color allows for easier object identification and differentiation. : Probabilistic image colorization. : Instance-aware image colorization.
