Content Based Medical Image Retrieval

Modern healthcare relies heavily on medical imaging, and as a result of its extensive use, image databases, picture archiving, and picture communication systems have been developed. Medical picture data is growing quickly due to technical advancements in the sector. These image collections provide a chance for research, teaching, and diagnosis based on evidence. As a result, suitable techniques for searching the collections for pictures with traits like the cases of interest are needed. Nevertheless, because each image in the database is enormous, processing them usually takes a lot of time. This makes retrieving medical images for diagnosis more challenging and time-consuming. Therefore, developing effective techniques for image retrieval from medical imaging collections is essential. Text that describes the scene is a major component of the traditional image retrieval techniques. They are hence keyword-based search techniques. Tracing each medical photograph by each individual scene is challenging and time-consuming. Therefore, rather than using text-based keywords to index medical photos, visual queries like colour, texture, and shape are used. Content-based medical image retrieval (CBMIR) has been a burgeoning field of study for the past 20 years. The three primary components of the CBMIR system are similarity measurement, feature extraction, and pre-processing. However, because medical images have unique properties, some of the CBMIR approaches yield disappointing results. Hence, developing effective techniques with higher retrieval accuracy and shorter retrieval times is the primary challenge of CBMIR.
