Color image analysis in optical microscopy [PDF]
Proceedings, annual meeting, Electron Microscopy Society of America, 1996 Most of the applications in microscopic image analysis are still solved by a heuristic method that focuses on the specificity of each problem. This is particularly true for applications involving color images. Because of this, the design of robust algorithms has remained time consuming and is usually performed by an image analysis expert with many ...

NEW METHOD USING IMAGE ANALYSIS TO MEASURE GINGIVAL COLOR
Journal of Dentistry Indonesia, 2015 For many years, observation of gingival color has been a popular area of dental research. However these methods are hard to analyze for any other than the different base conditions and colors. Thus we introduced an alternative method using image analysis
