Barred galaxies constitute a major fraction of all disk galaxies. For example, bars can be found in all types of disk galaxies, from the earliest to the latest stages of the Hubble sequence.

Thus, the class of quenching models is sufficient to explain the full range of morphological types observed for quenched galaxies. Elliptical galaxies, for example, are believed to be formed through major mergers 2, whereas disk-dominated galaxies cannot have undergone recent major mergers, as such mergers would have severely disrupted their shape 3. In turn, galaxy morphology can be used to provide an independent test of the two proposed scenarios for galaxy formation. For example, the Sloan Digital Sky Survey (SDSS) will produce more than 50,000,000 images of galaxies in the near future 1. We demonstrate that our proposed approach has better performance compared with the particle swarm optimization (PSO) and genetic algorithm (GA) methods.Īstronomy has become an immensely data-rich field. Our experiments were performed using the EFIGI catalogue, which contains about 5000 galaxies images with different types (edge-on spiral, spiral, elliptical and irregular). In the second stage, the similarity between the features of the queried galaxy image and the features of other galaxy images is computed. The proposed method consists of two stages, in the first stage, a set of features is extracted based on shape, color and texture descriptors, then a binary sine cosine algorithm selects the most relevant features. Therefore, this paper proposes an image-retrieval method to detect the type of galaxies within an image and return with the most similar image. However, in some situations, the aim is not only to determine the type of galaxy within the queried image, but also to determine the most similar images for query image.

Currently, there are several classification methods proposed to detect galaxy types within an image. This paper presents a new approach for the automatic detection of galaxy morphology from datasets based on an image-retrieval approach.
