Scene text removal via cascaded text stroke detection and erasing
AbstractRecent learning-based approaches show promising performance improvement for the scene text removal task but usually leave several remnants of text and provide visually unpleasant results. In this work, a novel end-to-end framework is proposed based on accurate text stroke detection. Specifically, the text removal problem is decoupled into text stroke detection and stroke removal; we design separate networks to solve these two subproblems, the latter being a generative network. These two networks are combined as a processing unit, which is cascaded to obtain our final model for text removal. Experimental results demonstrate that the proposed method substantially outperforms the state-of-the-art for locating and erasing scene text. A new large-scale real-world dataset with 12,120 images has been constructed and is being made available to facilitate research, as current publicly available datasets are mainly synthetic so cannot properly measure the performance of different methods.
Intravenous thrombolysis (IV –rtPA) has been suggested as a potential cause of myocardial infarction (MI) after acute ischemic stroke (AIS), with randomized clinical trials showing a higher number of cardiac events within the thrombolysis group. We assessed the prevalence and MI mechanisms after IV–rtPA for AIS.
Physical therapists generally set gait speed (parameter to understand walking ability) as a primary goal for rehabilitation in post-stroke patients. As per reported data, 0.16 m/s is the minimal clinically important difference in gait speed among subacute stroke patients.1 Post-stroke gait speed is associated with the range of activities of daily living and quality of life, and its improvement requires intensive rehabilitation.2–4 In gait cycle, at the initial contact phase, the ankle dorsiflexion angle (ADFA) provides a stable gait performance.
Mechanical thrombectomy (MT) has become leading treatment option for acute ischemic stroke (AIS) due to large vessels occlusion (LVO). Platelet counts may affect outcome in patients with AIS or transient ischemic attack. The aim of our study was to determine the influence of thrombocytopenia on the safety and efficacy of MT in patients with AIS due to anterior circulation LVO.

We described how the flow of neurological emergencies was affected by the pandemic impact.MethodsWe analyzed accesses to the Emergency Department (ED) of the “Maggiore della Carità” Hospital, Piedmont, Italy, during a period of 8 months (COVID time; March to May 2020 and October 2020 to February 2021) and analyzed the admissions to the Neurology Unit and the underlying diagnosis. We also evaluated potential changes in the treatment of acute ischemi c stroke in the same period. These variables were compared with two equivalent periods of time (2019–2020; 2018–2019).ResultsDuring the COVID...
DESPITE growing doubts about their safety, supplements remain massively popular in the UK. The risks associated with supplements generally occur at high doses, but prolonged use of some vitamins may also pose risks. One popular vitamin has been shown to increase the risk of haemorrhagic stroke by 22 percent, according to a study.
Glob Health Med. 2021 Dec 31;3(6):358-364. doi: 10.35772/ghm.2020.01113.ABSTRACTJapan ranks the highest globally, in terms of longevity. The average life expectancy was 81.4 years for men and 87.5 years for women in 2019. Such success in health is attributable to the substantial reduction in age-standardized mortality from cardiovascular diseases, especially stroke (136 per 105 in 1980 and 24 per 105 in 2015), when stroke mortality was the highest in the world between the 1960s and the 1990s. On the other hand, ischemic heart disease mortality was the lowest in the world between the 1960s and the 1980s and has continued to...
