After classification of satellite image post processing performed to improve quality of classification, such as recoding, reclass, sieve and filtering etc. The images taken are in the form of pixel and the process of changing it into digital images that make sense is known as image classification. Download PDF Info Publication number ... ICM 310 may compare the actual number of pixels encoded with the digital image with the classification rules, and determine whether the digital image should be stored as a high quality image, medium quality image, or low quality image. All the channels including ch3 and ch3t are used in this project. Human workers currently employ the traditional assessment method and classification of cocoa beans, which requires a significant amount of time. In the last accuracy assessed for classified satellite image using accuracy assessment tool, this process performed to assess the quality of satellite image to accept the classified images. /F1 6 0 R endstream Exposing Digital Image Forgeries by Illumination Color Classification Abstract: For decades, photographs have been used to document space-time events and they have often served as evidence in courts.
