Scene Text Detection of Curved Text Using Gradiant Vector Flow MethodIJTET Journal
Abstract--Text detection and recognition is a hot topic for researchers in the field of image processing and multimedia. Content based Image Retrieval (CBIR) community fills the semantic gap between low-level and high-level features. For text detection and extraction that achieve reasonable accuracy for multi-oriented text and natural scene text (camera images), several methods have been developed. In general most of the methods use classifier and large number of training samples to improve the accuracy in text detection. In general, connected components are used to tackle the multi-orientation problem. The connected component analysis based features with classifier training, work well for achieving better accuracy when the images are highly contrast. However, when the same methods used directly for text detection in video it results in disconnections, loss of shapes etc, because of low contrast and complex background. For such cases, deciding geometrical features of the components and classifier is not that easy. To overcome from this problem the proposed research uses Gradiant Vector Flow and Grouping based Method for Arbitrarily Oriented Scene text Detection method. The GVF of edge pixels in the Sobel edge map of the input frame is explored to identify the dominant edge pixels which represent text components. The method extracts dominant pixel’s edge components corresponding to the Sobel edge map, which is called Text Candidates (TC) of the text lines. Experimental results on different datasets including text data that is oriented arbitrary, non-horizontal text data also horizontal text data, Hua’s data and ICDAR-03 data (Camera images) show that the proposed method outperforms existing methods.
TEXT DETECTION AND EXTRACTION FROM VIDEOS USING ANN BASED NETWORKijscai
With fast intensification of existing multimedia documents and mounting demand for information indexing and retrieval, much endeavor has been done on extracting the text from images and videos. The prime intention of the projected system is to spot and haul out the scene text from video. Extracting the scene text from video is demanding due to complex background, varying font size, different style, lower resolution and blurring, position, viewing angle and so on. In this paper we 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. Text is grouped by constructing the minimum spanning tree with the use of bounding box distance.
In the present paper, electroencephalogram (EEG)
data have been used to human identification by computing
sample entropy and graph entropy as feature extractions. Used
two classifier types, which are K-Nearest Neighbors (K-NN) and
Support Vector Machine (SVM). Python and Matlab software
were used in this study and EEG data was collected by UCI
repository . Matlab used when Thirteen channels was applied as
feature extraction . The experimental results show that, Python
software classifies the EEG-UCI data better than MATLAB
environment software where the accuracy of KNN and SVM
were 85.2% and 91.5% respectively.
Handwritten and Machine Printed Text Separation in Document Images using the ...Konstantinos Zagoris
In a number of types of documents, ranging from forms to archive documents and books with annotations, machine printed and handwritten text may be present in the same document image, giving rise to significant issues within a digitisation and recognition pipeline. It is therefore necessary to separate the two types of text before applying different recognition methodologies to each. In this paper, a new approach is proposed which strives towards identifying and separating handwritten from machine printed text using the Bag of Visual Words paradigm (BoVW). Initially, blocks of interest are detected in the document image. For each block, a descriptor is calculated based on the BoVW. The final characterization of the blocks as Handwritten,Machine Printed or Noise is made by a Support Vector Machine classifier. The promising performance of the proposed approach is shown by using a consistent evaluation methodology which couples meaningful measures along with a new dataset.

IDENTIFICATION OF IMAGE SPAM BY USING LOW LEVEL & METADATA FEATURES IJNSA Journal
Spammers are constantly evolving new spam technologies, the latest of which is image spam. Till now research in spam image identification has been addressed by considering properties like colour, size, compressibility, entropy, content etc. However, we feel the methods of identification so evolved have certain limitations due to embedded obfuscation like complex backgrounds, compression artifacts and wide variety of fonts and formats .To overcome these limitations, we have proposed 2 methodologies(however there can be more). Each methodology has 4 stages. Both the methodologies are
almost similar except in the second stage where methodology I extracts low level features while the other extracts metadata features. Also a comparison between both the methodologies is shown. The method works on images with and without noise separately. Colour properties of the images are altered so that
OCR (Optical Character Recognition) can easily read the text embedded in the image. The proposed
methods are tested on a dataset of 1984 spam images and are found to be effective in identifying all types of spam images having (1) only text, (2) only images or (3) both text and images. The encouraging experimental results show that the methodology I achieves an accuracy of 92% while the other achieves an accuracy of 93.3%.

Our proposed work involves recognizing text and product label reading from portable entities intended for Visionless Persons using Raspberry Pi 3, ultrasonic sensor. Raspberry Pi 3 is the controller used in the proposed device. GPS is fixed in the system and it is used to find the exact location of the person in terms of longitude and latitude, this information is sent to the caretaker through e mail. The caretaker can use the latitude and longitude to find the address on Google Maps. The camera is used to identify the obstacle or object ahead and the output is told to the blind user in speech form. The camera also identifies objects with words on them, using image processing these images are converted to text, and using Tesseract the text is converted to speech, thus giving the speech output to the blind about what is written on the object. RF ID is used to find the stick using tags. The buzzer goes ON to identify the location of the stick. A threshold value for distance between the user and the stick is set, when the distance is less than the threshold value, the buzzer sound increases. Arunkumar. V | Aswin M. D | Bhavan. S | Gopinath.

Automated systems for understanding display boards are finding many applications useful in guiding tourists, assisting visually challenged and also in providing location aware information. Such systems require an automated method to detect and extract text prior to further image analysis. In this paper, a methodology to detect and extract text regions from low resolution natural scene images is presented. The proposed work is texture based and uses DCT based high pass filter to remove constant background. The texture features are then obtained on every 50x50 block of the processed image and potential text blocks are identified using newly defined discriminant functions. Further, the detected text blocks are merged and refined to extract text regions. The proposed method is robust and achieves a detection rate of 96.6% on a variety of 100 low resolution natural scene images each of size 240x320.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
