Abstract: In the intricate field of medical imaging, the analysis of image content plays a pivotal role in classification, retrieval, and indexing tasks, as well as in recognising objects and different settings within the image. While innovative, traditional methods typically fail to efficiently and accurately process medical image databases' massive and complicated data. Due to this shortcoming, discrete wavelet coefficients-bag of visual words-contour-local binary pattern (DWC-BoVW-Contour-LBP) relevance fusion was developed. A trimmed mean filter and contrast limited adaptive histogram equalisation (CLAHE) remove noise and boost contrast to optimise the image for feature extraction in this novel method. The system carefully extracts low-level frequency features using discrete wavelet transform (DWT), textural features using local binary pattern (LBP), shape features using contour analysis, and visual features using bag of visual words (BoVW). Pixel image fusion is used to combine various features into a complete picture. Patch Sorensen similarity measurement ranks database photos by query resemblance and selects the top 10 most similar images. The algorithm's precision, F-score, and recall were superior in the TCIA-CT database, showing a substantial progress in content-based medical image retrieval (CBMIR).
