Summary:The invention discloses a low-illumination image enhancement method for a wireless capsule endoscope, and belongs to the field of computer vision. The method comprises the following steps: carrying out illumination component extraction on a V component of an image by adopting a multi-scale fast guide filtering function; calculating a brightness enhancement function parameter T from the illumination component by adopting an OTSU method; fitting a brightness enhancement function on the basis of the parameter T and a Weber-Fechner theory; a wavelet function is used for saturation adjustment; based on a merging channel, converting to an RGB color space to realize integral enhancement of the image; experimental results show that compared with an existing method, the method has the advantages that quantitative evaluation index mean value, standard deviation, information entropy and image quality evaluation of image enhancement are improved; besides, the verification effects of the enhanced image are averagely impro
