Computer Vision News - January 2017
16 Computer Vision News Focus on… 1. The marker image; the peaks in the marker image should identify the location of spots objects in the image you want to emphasize. In the example below, the region of 17 and 13 are marked as spots objects to identify. 2. The morphology reconstruction of the image is: The Grayscale Morphological reconstruction processes thresholds of the two images above (the mask and the marker) with a value ranging from 9 through 17. At each threshold value it performs morphological reconstruction, finally taking the max value from the 17 resulting reconstructions. To further understand this, let’s dive into threshold values 10 and 11. When thresholding by 11 the marker image shows only two regions - the areas with original values 12 and 16, thus only those will be reconstructed at the 11 iteration. The Mask after thresholding by 11: However, when thresholding by 10, one additional spot appears in the marker image, so that it will be reconstructed. The grayscale value in the resulting areas is determined by the values appearing in the mask image. Focus on…
