Interactive preliminary classification is a process in which a human operator manually labels a subset of the image pixels, and then uses these labeled pixels to guide an algorithm in automatically classifying the remaining pixels in the image. This approach combines the strengths of both manual and automatic classification methods, by allowing a human operator to provide initial guidance on the classification while also leveraging the computational power of an algorithm to classify the remaining pixels in the image.
The process of interactive preliminary classification typically begins with the human operator manually selecting and labeling a subset of the image pixels, called the training set. This training set is then used to train an algorithm, such as a decision tree or a support vector machine, to classify the remaining pixels in the image. The algorithm uses the training set to identify patterns and features that are specific to each class, and then applies these patterns and features to the remaining pixels in the image to classify them.
Interactive preliminary classification is useful in situations where the image data is complex or difficult to classify, and where manual annotation would be time-consuming and resource-intensive. By allowing a human operator to provide initial guidance on the classification, the algorithm is able to more accurately classify the remaining pixels in the image.
The operator can also use different tools such as decision tree, random forest and support vector machine to classify the image pixels.
Overall, interactive preliminary classification is a powerful method for image classification, as it combines the strengths of both manual and automatic classification methods to provide a more efficient and accurate method for classifying complex or difficult image data.
