6. steam on-site identification system as claimed in claim 5, it is characterised in that:
The dynamic processing equipment includes kind detecting unit, for receiving refrigerator inside image, to the refrigerator inside image
Noise type analysis is carried out with the maximum noise type of noise amplitude in the determination refrigerator inside image using as mainly making an uproar
The output of sound type；
Wherein, the noise type in the refrigerator inside image includes internal noise, the transmission channel that sensitive components generates
Grain noise caused by interference noise, electrical machinery movement bring jittering noise and photosensitive material.
7. steam on-site identification system as claimed in claim 6, it is characterised in that:
The dynamic processing equipment includes model customization unit, is connect with the kind detecting unit, described main for receiving
Noise type, and median filtering template is determined based on the main noise type.
8. steam on-site identification system as claimed in claim 7, it is characterised in that:
The dynamic processing equipment includes object judgement unit, is connect with the kind detecting unit, for judging the refrigerator
Objective contour in internal image.
9. steam on-site identification system as claimed in claim 8, it is characterised in that:
The dynamic processing equipment includes pixel value analytical unit, respectively with the model customization unit and the object judgement list
Member connection, for being according to it based on the median filtering template to each contour pixel for forming the objective contour
Pixel distribution in the median filtering window at center determines different filtering strategies, it is described based on the median filtering template according to
The pixel distribution in median filtering window centered on it determines that different filtering strategies include: when in median filtering window
When object pixel quantity is more than or equal to the non-targeted pixel quantity in median filtering window, the pixel value of each object pixel is taken
Pixel value of the mean value as the contour pixel, when the object pixel quantity in median filtering window is less than in median filtering window
Non-targeted pixel quantity when, take pixel value of the mean value of the pixel value of each non-targeted pixel as the contour pixel；
Wherein, the pixel value analytical unit is also used to be not belonging to each of the objective contour in the refrigerator inside image
A non-contour pixel, based on the median filtering template according to the picture of all pixels in the median filtering window centered on it
Pixel value of the mean value of element value as the non-contour pixel；The pixel value analytical unit exports dynamically processing image.
