ALPHABETS IMAGE IDENTIFICATION USING ADVANCED LOCAL BINARY PATTERN AND CHAIN CODE ALGORITHM

نویسندگان

چکیده

Optical Character Recognition (OCR) is a method for computer to process an image that contains some text and then try find any characters in image, convert it digital text. In this research, Advanced Local Binary Pattern Chain Code algorithm will be tested identify alphabets the image. Several preprocessing are also needed, such as transformation, rescaling, grayscale conversion, edge detection thinning.

Image Retrieval using Quantized Local Binary Pattern

Image retrieval is one of the main topics in the field of computer vision and pattern recognition. Local descriptors are gaining more and more recognition in recent years as these descriptors are capable enough to identify the unique features, which suitably and uniquely describe any image for recognition and retrieval. One of the popular and efficient frame works for capturing texture informat...

Ultrasound Image Despeckling using Local Binary Pattern Weighted Linear Filtering

Speckle noise formed as a result of the coherent nature of ultrasound imaging affects the lesion detectability. We have proposed a new weighted linear filtering approach using Local Binary Patterns (LBP) for reducing the speckle noise in ultrasound images. The new filter achieves good results in reducing the noise without affecting the image content. The performance of the proposed filter has b...

Image Retrieval Technique Using Local Binary Pattern (LBP)

The increased need of content based image retrieval technique can be found in a number of different domains such as Data Mining, Education, Medical Imaging, Crime Prevention, Weather forecasting, Remote Sensing etc. An image retrieval system allows us to browse, search and retrieve the images. In early days because of very large image collections the manual annotation approach was more difficul...

Using Local Binary Pattern Operators for Colour Constant Image Indexing

The Local Binary Pattern (LBP) operator computes a local texture measure that is invariant to monotonic transformations of the image grey-scale. As a result of this property, calculating the LBP value in each channel of a colour image results in a triplet of values that are invariant to changes in illumination colour. Previous research has shown that histograms of grey-scale LBP values, and his...

An Advanced Digital Image Forgery Detection via Local Binary Pattern and Haralick Features

Nowadays, authorizing the genuineness of an image is a big challenge. For ensuring the trustworthiness of images, a secure hashing method is developed. This method detects the tampering like addition, removal and replacement of any object from the image, unusual color modifications, resizing, and image compression and especially locates the forged area. A hash sequence is generated by extractin...
