Texture is a critical aspect for visualizing smoothness or coarseness in images.
Digital image processing involves several stages, including pre-processing, enhancement, transformation, and classification.
Both supervised and unsupervised classifications have their applications and relevance in remote sensing image analysis.
The arrangement and frequency of tonal variation in an image that helps determine the overall smoothness or coarseness of features.
The process of converting image coordinates to ground coordinates to remove distortions caused by sensor geometry.
A classification method where an analyst uses a priori knowledge to identify training sites and classify pixels based on their DN values.
A classification method that groups DN values without the need for prior knowledge of specific land cover types.
A tool used for assessing the accuracy of a classification by comparing classified data against reference data.
