    Celem projektu realizowanego w Katedrze Automatyki jest stworzenie wydajnego narzędzia wspomagającego proces nadzoru przestrzeni i obiektów publicznych, w oparciu o automatyczną analizę obrazów cyfrowych. Przy założeniu szeroko pojętej ogólności zagrożeń, które mają być wykrywane, konstrukcja programu do automatycznego wspomagania nadzoru nie jest zagadnieniem trywialnym, ze względu na nieprzewidywalną wielowariantowość obserwowanych sytuacji. Opracowanie efektywnego systemu wymaga rozwiązania szeregu zagadnień, skomplikowanych od strony koncepcyjnej i trudnych w realizacji algorytmicznej. Zadaniem inteligentnego systemu wspomagania monitoringu jest wskazanie obsłudze systemu sytuacji potencjalnie podejrzanych z punktu widzenia przyjętych kryteriów bezpieczeństwa. W celu przezwyciężenia pojawiających się tu trudności tworzone są algorytmy, których działanie opiera się nie tylko na przetwarzaniu i analizie obrazów, ale także na próbach automatycznego rozumienia znaczenia obserwowanych scen, czyli imitowanych komputerowo elementach ludzkiego postrzegania i toku myślenia, związanego z ocenianym obrazem.The aim of the project realized in the Department of Automatics is to create an efficient tool to support the process of surveillance of public spaces and buildings based on automated image analysis. Assuming a wide scope of applications of developed tools, the design of the program to automatically support surveillance tasks is not a trivial problem, due to unforeseen circumstances and non-predicted situation. Developing an effective surveillance system requires addressing a number of issues, that are conceptually complex and require research and implementation of advanced algorithms. The goal of an intelligent monitoring system is to identify potentially suspicious circumstances according to assumed safety criteria. In order to overcome arising here difficulties there are created algorithms whose operation is based not only on processing and analyzing images, but also on imitating a human perception and understanding of the analyzed images

    Current practice and short-term outcomes of therapeutic mammaplasty in the international TeaM multicentre prospective cohort study

    Background: Therapeutic mammaplasty, which combines breast reduction and mastopexy techniques with tumour excision, may extend the boundaries of breast-conserving surgery and improve outcomes for patients, but current practice is unknown and high-quality outcome data are lacking. This prospective multicentre cohort study aimed to explore the practice and short-term outcomes of the technique. Methods: Consecutive patients undergoing therapeutic mammaplasty at participating centres between 1 September 2016 and 30 June 2017 were recruited to the study. Demographic, preoperative, operative, oncological and complication data were collected. The primary outcome was unplanned reoperation for complications within 30 days of surgery. Secondary outcomes included re-excision rates and time to adjuvant therapy. Results: Overall, 880 patients underwent 899 therapeutic mammaplasty procedures at 50 centres. The most common indications were avoidance of poor cosmetic outcomes associated with standard breast-conserving surgery (702 procedures, 78·1 per cent) or avoidance of mastectomy (379, 42·2 per cent). Wise-pattern skin incisions were the most common (429 of 899, 47·7 per cent), but a range of incisions and nipple–areola pedicles were used. Immediate contralateral symmetrization was performed in one-third of cases (284 of 880, 32·3 per cent). In total, 205 patients (23·3 per cent) developed a complication, but only 25 (2·8 per cent) required reoperation. Median postoperative lesion size was 24·5 (i.q.r. 16–38) mm. Incomplete excision was seen in 132 procedures (14·7 per cent), but completion mastectomy was required for only 51 lesions (5·7 per cent). Median time to adjuvant therapy was 54 (i.q.r. 42–66) days. Conclusion: Therapeutic mammaplasty is a safe and effective alternative to mastectomy or standard breast-conserving surgery. Further work is required to explore the impact of the technique on quality of life, and to establish cost-effectiveness

    Therapeutic mammaplasty is a safe and effective alternative to mastectomy with or without immediate breast reconstruction

    Background: Therapeutic mammaplasty (TM) may be an alternative to mastectomy, but few well designed studies have evaluated the success of this approach or compared the short-term outcomes of TM with mastectomy with or without immediate breast reconstruction (IBR). Data from the national iBRA-2 and TeaM studies were combined to compare the safety and short-term outcomes of TM and mastectomy with or without IBR. Methods: The subgroup of patients in the TeaM study who underwent TM to avoid mastectomy were identified, and data on demographics, complications, oncology and adjuvant treatment were compared with those of patients undergoing mastectomy with or without IBR in the iBRA-2 study. The primary outcome was the percentage of successful breast-conserving procedures in the TM group. Secondary outcomes included postoperative complications and time to adjuvant therapy. Results: A total of 2916 patients (TM 376; mastectomy 1532; mastectomy and IBR 1008) were included in the analysis. Patients undergoing TM were more likely to be obese and to have undergone bilateral surgery than those having IBR. However, patients undergoing mastectomy with or without IBR were more likely to experience complications than the TM group (TM: 79, 21·0 per cent; mastectomy: 570, 37·2 per cent; mastectomy and IBR: 359, 35·6 per cent; P < 0·001). Breast conservation was possible in 87·0 per cent of patients who had TM, and TM did not delay adjuvant treatment. Conclusion: TM may allow high-risk patients who would not be candidates for IBR to avoid mastectomy safely. Further work is needed to explore the comparative patient-reported and cosmetic outcomes of the different approaches, and to establish long-term oncological safety
