The PCAL technique is used to classify the HSI patterns that are important in remote sensing applications using this pattern collection. The EDP is used to merge and classify different labels for each image sample, and this algorithm expresses the textural information. Initially, distributed intensity filtering (DIF) is used to eliminate noise from the image, and then histogram equalization (HE) is used to improve the image quality. This paper extends that work into the novel pixel-certainty activity learning (PCAL) based on the information about textural patterns obtained from the extended differential pattern (EDP). Previously, we focused on the extraction of clear textural pattern information by using the extended differential pattern-based relevance vector machine (EDP-AL). The uncertainty exists pixel variations make the heuristics-based AL fail to handle the remote sensing image classification. The heuristics-based AL provides better results with the inheritance of contextual information and the robustness to noise variations. The building of an efficient training set iteratively in active learning (AL) approaches improves classification performance. With the limited financial resources and the high intra-class variations, the earlier proposed algorithms failed to handle the sub-optimal dataset. An accurate identification of objects from the acquisition system depends on the clear segmentation and classification of remote sensing images.
