Description: 为了提取区域边界，可以对图像直接运用一阶微商算子或二阶微商算子，然后根据各像点处的微商幅值或其他附加条件判定其是否为边界点。如果图像中含有较强噪声，直接进行微商运算将会出现许多虚假边界点。-.Using the feature of distinct edge contour existing between the text and the background regions in color images, a novel text extraction algorithm—CEMA(Color-edge detection, Morphology, logic operator“AND”) is proposed in this thesis for video images.

Description: 数据库安全 数据库安全 数据库安全 数据库安全-We present a novel method for key term extraction from text
documents. In our method, document is modeled as a graph
of semantic relationships between terms of that document.
We exploit the following remarkable feature of the graph:
the terms related to the main topics of the document tend to
bunch up into densely interconnected subgraphs or communities,
while non-important terms fall into weakly interconnected
communities, or even become isolated vertices. We
apply graph community detection techniques to partition
the graph into thematically cohesive groups of terms. We
introduce a criterion function to select groups that contain
key terms discarding groups with unimportant terms. To
weight terms and determine semantic relatedness between
them we exploit information extracted from Wikipedia. Platform: |

Description: In Year 2012, A. Thilagavathy performed a work," TEXT DETECTION AND EXTRACTION FROM VIDEOS USING ANN BASED NETWORK". In this paper Author put forward a hybrid method where the two most Well-liked text extraction techniques i.e. region based method and connected component (CC) based method comes together. Initially the video is split into frames and key frames obtained. Text region indicator (TRI) is being developed to compute the text prevailing confidence and candidate region by performing binarization. Artificial Neural network (ANN) is used as the classifier and Optical Character Recognition (OCR) is used for character verification. Platform: |

-Image inpainting refers to restore the color information of the damaged region in the image or remove the
unnecessary object in the image. A method is introduced to compute the main direction of the texture and complete
the image based on wavelet transform. The core of the algorithm relies on using texture detection in a coarse-to-fine
scheme. Experimental results show that the algorithm can obtain the satisfied restoration video frames.

Description: object classification using recognized scene text in natural images. While the state-of-the-art relies on visual cues only, this paper is the first work which proposes to combine textual and visual cues. Another novelty is the textual cue extraction. Unlike the state-of-the-art text detection methods, we focus more on the background instead of text regions. Once text regions are detected, they are further processed by two methods to perform text recognition Platform: |
