A Combined Approach on RBC Image Segmentation through Shape Feature Extraction
1. Image Denoising | 1.1 Find the rough position of each grid line; | 1.2 Remove the noise using median filtering locally. | 2. Cell Extraction Individually | 2.1 Guided boundary contour tracing; | 2.2 Cell Extraction through 4-neighborhood region growing. | 3. Shape from Shading Using Linear Approximation | 3.1 Image Irradiance Equation Deductio; | 3.2 3-D Shape Reconstructing. | 4. Computing RBC shape surface feature | 4.1 Compute mean curvature and Gaussian curvature using image convolution; | 4.2 Set a threshold for this two curvature. | 5: Segmentation through multiscale surface fitting | More details is in Section 6: Experiment. |
