Figure 4From: Color edges extraction using statistical features and automatic threshold technique: application to the breast cancer cells Spatial relationship between the current pixel (x,y) and its neighbors in the blocs W xy . (a) The neighborhood N(x,y) of the current pixel (x,y), (b) weight coefficients for calculating the (ES1, ES2, ES3, ES4, ES5, ES6, ES7 and ES8) edge strengths of potential edge patterns.Back to article page
