title: [A study on computer assistant real-time diagnosis for micro-focused lesion of esophagus].
abstract: OBJECTIVE
  To investigate the effect of computer-assisted real-time diagnosis on esophagus micro-focused lesion based on the change of grey shade.
  
  
  METHODS
  Comparison algorithm for the hue saturation mean value and integral algorithm for the vibration frequency of grey color shade were used to analyze the esophagus images collected by quick and real-time operation.
  
  
  RESULTS
  The research results showed that, the image-operative software, based on the two kinds of arithmetic mentioned above, had some effects on discriminating the esophagus micro-focused lesions, such as esophagitis, early carcinoma of esophagus, middle-late carcinoma of esophagus and atypical hyperplasia of esophagus one another.
  
  
  CONCLUSIONS
  The software could be used as a kind of assisted diagnostic measure to screen out the micro-focused lesion of esophagus effectively.
