Interactive patternrecognition concepts and techniques are applied to problems with structured output;i.e., problems in which the result is not just a simple class label, but a suitable structure of labels. For illustration purposes (a simplification of) the problem of Human Karyotyping is considered. Results show that a) taking into account label dependencies in a karyogram significantly reduces the classical (non-interactive) chromosome label prediction error rate and b) they are further improved when interactive processing is adopted.

An incremental approach to the discriminative common vector (DCV) method for imagerecognition is considered. Discriminative projections are tackled in the particular context in which new training data becomes available and learned subspaces may need continuous updating. Starting from incremental eigendecomposition of scatter matrices, an efficient updating rule based on projections and orthogonalization is given. the corresponding algorithm has been empirically assessed and compared to its batch counterpart. the same good properties and performance results of the original method are kept but with a dramatic decrease in the computation needed.

We study the application of minimum description length (MDL) inference to estimate patternrecognition models for machine translation. MDL is a theoretically-sound approach whose empirical results are however below those of the state-of-the-art pipeline of training heuristics. We identify potential limitations of current MDL procedures and provide a practical approach to overcome them. Empirical results support the soundness of the proposed approach.

image binarization is a common operation in the preprocessing stage in most Optical Music recognition (OMR) systems. the choice of an appropriate binarization method for handwritten music scores is a difficult problem. Several works have already evaluated the performance of existing binarization processes in diverse applications. However, no goal-directed studies for music sheets documents were carried out. this paper presents a novel binarization method based in the content knowledge of the image. the method only needs the estimation of the staffline thickness and the vertical distance between two stafflines. this information is extracted directly from the gray level music score. the proposed binarization procedure is experimentally compared with several state of the art methods.

Wearable cameras can daily gather large amounts of image data that require powerful image indexing and retrieval techniques in order to find the information of interest. In this work, we address the indexing problem of egocentric data by exploring the relevance of different information sources provided by Convolutional Neural Networks (CNN) combined withimage metadata. the proposed method was tested on a public egocentric dataset of 45.000 images and gave encouraging results.

the impact of using different lossless compression algorithms when compressing biometric iris sample data from several public iris databases is investigated. In particular, the application of dedicated lossless image codecs (lossless JPEG, JPEG-LS, PNG, and GIF), lossless variants of lossy codecs (JPEG2000, JPEG XR, and SPIHT), and a few general purpose file compression schemes is compared. We specifically focus on polar iris images (as a result after iris detection, iris extraction, and mapping to polar coordinates). the results are discussed in the light of the recent ISO/IEC FDIS 19794-6 standard and IREX recommendations.

this paper presents an approach to the identification of playing cards and counting of chips in a poker game environment, using an entry-level webcam and computer vision methodologies. Most of the previous works on playing cards identification rely on optimal camera position and controlled environment. the presented approach is intended to suit a real and uncontrolled environment along with its constraints. the recognition of playing cards lies on template matching, while the counting of chips is based on colour segmentation combined withthe Hough Circles Transform. Withthe proposed approach it is possible to identify the cards and chips in the table correctly. the overall accuracy of the rank identification achieved is around 94%.

In this paper, a semi-supervised approach based on probabilistic relaxation theory is presented. Focused on image segmentation, the presented technique combines two desirable properties;a very small number of labelled samples is needed and the assignment of labels is consistently performed according to our contextual information constraints. Our proposal has been tested on medical images from a dermatology application with quite promising preliminary results. Not only the unsupervised accuracies have been improved as expected but similar accuracies to other semi-supervised approach have been obtained using a considerably reduced number of labelled samples. Results have been also compared with other powerful and well-known unsupervised image segmentation techniques, improving significantly their results.
