Finally the gradient direction histograms of each zone are calculated and the local direction histograms of the approximation component are considered as the features of the character sample image.The proposed method is tested on the recently developed off-line Tibetan handwritten character sample database.The experimental results demonstrate the effectiveness and efficiency of the proposed feature extraction method.Furthermore compared with the detail components the approximation component contributes more to the recognition accuracy.展开更多

Taking two different Polish novels as examples, the author deals with the metaphor of ruins, remains, and ashes to define the ontological status of the world in two texts. In the first text, Piotr Szewc＇s annihilation brings the positive vision of ruin as a kind of fragile and finite being which needs love and care. In the second text, Piotr Pazinski＇s Pensjonat shows that ruin is only a negative aspect of reality which is illegible and empty. The main concern of the text is to oppose those two visions and make a conclusion about the dialectic of the ruin.展开更多
