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.

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.

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.

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%.

Feature selection is a topic of growing interest mainly due to the increasing amount of information, being an essential task in many machine learning problems with high dimensional data. the selection of a subset of relevant features help to reduce the complexity of the problem and the building of robust learning models. this work presents an adaptation of a recent quadratic programming feature selection technique that identifies in one-fold the redundancy and relevance on data. Our approach introduces a non-probabilistic measure to capture the relevance based on Minimum Spanning Trees. three different real datasets were used to assess the performance of the adaptation. the results are encouraging and reflect the utility of feature selection algorithms.

We show how to cast the problem of specularity subtraction as blind source separation from polarisation images. We commence by summarizing the relationships between the specular and diffuse reflection components for polarised images. We show how to use singular value decomposition for component separation. In particular, we show how reliable results can be obtained using three images acquired with different polariser angles under diffuse reflection. the proposed method can be used as the preprocessing step in shape from shading, segmentation, reflectance estimation and many other computer vision applications.

We present a novel computational framework for automatic classification method by symmetries, for periodic images applied to content based image retrieval. the existing methods have several drawbacks because of the use of heuristics. these methods have shown low classification values when images exhibit imperfections due to the fabrication or the hand made process. Also, there is no way to give some computation of the classification goodness-of-fit. We propose to obtain an automatic parameter estimation for symmetry analysis. thus, the image classification is redefined as distances computation to the prototypes of a set of defined classes. Our experimental results improves the state of the art in wallpaper classification methods.
