    • A method for processing an image, including: identifying a group of keypoints in the image; for each keypoint, calculating a corresponding descriptor array including plural array elements, each array element storing values taken by a corresponding color gradient histogram of a respective sub-region of the image in the neighborhood of the keypoint; for each keypoint, subdividing the descriptor array in at least two sub-arrays each including a respective number of elements of the descriptor array, and generating a compressed descriptor array including a corresponding compressed sub-array for each of the at least two sub-arrays, each compressed sub-array obtained by compressing the corresponding sub-array by vector quantization using a respective codebook; exploiting the compressed descriptor arrays of the keypoints for image analysis. For each keypoint of the group, the subdividing is based on correlation relationships among color gradient histograms with values stored in the elements of the descriptor array of each keypoint.

    • A method is disclosed for providing a telecare service to a patient. According to the method, at least one sensor installed in a domestic environment of the patient detects a datum relating to either the domestic environment or an interaction between patient and domestic environment. Based on the detected datum, an anomaly in the domestic environment or in the interaction between patient and domestic environment is detected. Then, a predefined question uniquely associated with the detected anomaly is selected for generating a questionnaire to be submitted to the patient, with the purpose of determining the cause of the detected anomaly. Based on the patient's reply it is determined if the detected anomaly is a false anomaly and, in the affirmative, the predefined question associated to such false anomaly is excluded from the next questionnaire(s), even if the anomaly persists.

    • A method for controlling a heterogeneous wireless network (100) is proposed. The heterogeneous wireless network comprises at least one first base station (115) which manages communication of a plurality of first user equipments (125M) positioned in at least one first cell (105) and at least one second base station (120) which manages communication of a plurality of second user equipments (125p) positioned in at least one second cell (110). Moreover, in the heterogeneous network (100), for each first user equipment (125M) the at least one first base station (115) provides a respective first allocation information set over a respective first allocation time interval. Similarly, the at least one second base station (120) provides for each second user equipment (125p) a respective second allocation information set over a respective second allocation time interval. Furthermore, each first allocation information set and each second allocation information set define transmission resources for communications of each first user equipment (125M) and of each second user equipment (125M), respectively. In the heterogeneous wireless network (100), the at least one second cell (110) is at least partially comprised in the first cell (105). The method comprises the following steps. Said at least one first base station determines (305) a set of probably interfering first user equipments (125M) with at least one of the plurality of second user equipments (125p). Said step of determining the set of probably interfering first user equipments (125M) comprises the following steps. Comparing each second allocation information set with each first allocation information set having the first allocation time interval at least partially overlapped with the respective second allocation time interval, and identifying as a probably interfering first user equipment (125M) each first user equipment (125M) for which a correspondence is verified in said comparing allocation information sets. The method further comprises the following steps. Said at least one second base station (120) defines a detection time window in order to analyze univocal identifiers transmitted by probably interfering first user equipments (125M) in said set. The method comprises identifying (315) a subset of effectively interfering first user equipments (125M) with the plurality of second user equipments (125p). Said at least one first base station (115) modifies (325) said transmission resources for at least one first user equipment (125M) comprised in the subset of effectively interfering first user equipments (125M) in order to mitigate interferences.
