Bottom Line: The aim of this paper is to design an automatic system to identify the staining patterns based on block segmentation compared to the cell segmentation most used in previous research.Various feature descriptors and classifiers are tested and compared in the classification of the staining pattern of blocks and it is found that the technique of the combination of the local binary pattern and the k-nearest neighbor algorithm achieve the best performance.Relying on the results of block pattern classification, experiments on the whole images show that classifier fusion rules are able to identify the staining patterns of the whole well (specimen image) with a total accuracy of about 94.62%.

ABSTRACT
Indirect immunofluorescence based on HEp-2 cell substrate is the most commonly used staining method for antinuclear autoantibodies associated with different types of autoimmune pathologies. The aim of this paper is to design an automatic system to identify the staining patterns based on block segmentation compared to the cell segmentation most used in previous research. Various feature descriptors and classifiers are tested and compared in the classification of the staining pattern of blocks and it is found that the technique of the combination of the local binary pattern and the k-nearest neighbor algorithm achieve the best performance. Relying on the results of block pattern classification, experiments on the whole images show that classifier fusion rules are able to identify the staining patterns of the whole well (specimen image) with a total accuracy of about 94.62%.

Mentions: Typical fusion techniques, including majority rule (MR), WMR [41] and WSR [42], [43] (see Figure 7), will be used in this section to combine the results of block recognition. However, a critical point of these fusion rules is that different blocks belonging to the same well should be included in either the training set or the testing set, which guarantees that the final well pattern is determined by all the blocks belonging to this well image. So we randomly subdivided all the well images into two equal partitions and different blocks belonging to the same well were all in one partition. In the following, we briefly describe these fusion rules.
