Effective preprocessing of image data plays a pivotal role in enhancing the discriminative modeling capabilities in downstream machine learning tasks. This study investigates the significance of adequately mapping image data into a new feature space during the preprocessing phase, emphasizing its criticality in facilitating more robust and accurate models. While traditional methods such as signal/image processing transforms have been previously explored for this purpose, this study introduces a novel approach leveraging deep learning techniques. Specifically, convolutional and pooling layers are employed to process the image data, offering a more sophisticated and adaptive method for feature extraction and representation. By employing deep learning architectures, the preprocessing phase becomes more flexible and capable of capturing intricate patterns and structures within the data. Through empirical evaluation, our approach demonstrates significant improvements in discriminative modeling across various traditional machine learning approaches. This highlights the effectiveness and versatility of deep learning-based preprocessing in enhancing the performance of downstream tasks, showcasing its potential to advance the field of image data processing and analysis.
