Embodiment Construction
[0044] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0045] Such as figure 2 Shown, a kind of method of the present invention carries out pseudo-color processing to medical grayscale image signal specific steps are as follows:
[0046]Because medical images will cause some degradation during the process of acquisition, transmission and conversion, and are easily polluted by noise, therefore, the degraded medical images must be preprocessed first. Using a Gaussian (Gauss) low-pass filter, a Gaussian smoothing template is used during the template operation 1 16 1 2 1 2 4 2 ...
