Abstract

The invention discloses a remote sensing image feature extraction method and device based on a bat algorithm and normalized chromatic aberration. The method comprises the following steps: acquiring anaerial remote sensing image; optimizing the contrast of the remote sensing image by utilizing a bat algorithm; extracting features of the remote sensing image after contrast optimization based on thenormalized chromatic aberration; and carrying out filtering processing on the obtained feature map. The bat algorithm is used for enhancing the contrast of the remote sensing image, compared with a traditional gray histogram equalization method, the obtained image is more uniform in gray distribution and more obvious in contrast, in addition, the object is extracted according to the color features of the remote sensing image, the overall features of the object are completely reserved in the extraction result, and operation is easy.
