A Calculation Method of Cone Cell Density Based on Image Recognition

The invention relates to a cone-cell density calculation method based on image identification. The method mainly solves the prior problem that density counting of cone cells is performed manually and an eye-ground adaptive confocal laser scanning ophthalmoscope is used to obtain a visual cone-cell image and after the response frequency of the cone cells is determined, low-pass filtering is used for denoising processing so as to establish a two-valued sequence. A local maximum value corresponding to a non-zero area is searched for so that the central position of the cone cells is found. After automatic identification of the visual cone cells in the image is completed, the number of the cone cells in the image is obtained with the assistance of manual correction and finally the density counting of the cone cells is achieved. When the function which adopts a computer to counting automatically is compared with a manual counting method, the automatic calculation method is accurate, high in statistical speed, high in automation degree, checkable in analysis result and improved in detection efficiency. At the same time, a manual correction function is added so that on the basis of software analysis, error identification can be removed manually and missed cone cells can be added and thus caused result deviation is prevented.
