SELF-SUPERVISED LEARNING Fine-grained image classification remains challenging due to the large intra-class variance and small inter-class variance. I discovered that the overall objective of image classification procedures is “to automatically categorise all pixels in an image into land cover classes or themes” (Lillesand et al, 2008, p. 545). In this paper, we present a new architecture and an approach for unsupervised object recognition that addresses the above mentioned problem with fine tuning associated with pretrained CNN-based supervised deep learning approaches while allowing automated feature extraction. First, extensive experiments are conducted and show that, for a given dataset, the choice of the CNN architecture for feature extraction has a huge impact on the final clustering. Reclassify a raster based on grouped values 3. While deep learning strategies achieve outstanding results in computer vision tasks, one issue remains: The current strategies rely heavily on a huge amount of labeled data.
