Embodiment Construction
[0028] The present invention will be described in detail below with reference to the accompanying drawings, so that those skilled in the art can better understand the present invention. It should be noted that, without departing from the core idea of the present invention, those skilled in the art can make some improvements to the present invention, which all belong to the protection scope of the present invention.
[0029] like figure 1 As shown, the present invention provides a multi-threshold segmentation method for medical images based on interval iteration, including the following steps:
[0030] Step one, using mixed L 1 -L 0 The layer decomposition method obtains the base layer of the source image, and the decomposition model is:
[0031]
[0032] Given a source image I of size M×N. Among them, I B represents the base layer of the source image I, by computing L 1 The sparsity of the gradient get. I D (=I-I B ) represents the detail layer of the source im...
