چکیده

This paper presents an algorithm to segment text and picture in an image using two features based on the statistical distribution of the wavelet coe cients in high frequency bands. The algorithm breaks the image into blocks and classi es every block as background, text or picture according to the two features. The block size is variable so that the segmentation can be accurate at the boundary of two types and avoids misclassifying due to over-localized region analysis.

Breast abnormalities segmentation using the wavelet transform coefficients aggregation

Introduction: Breast cancer is the most common cancer among women in the world. The automatic detection of masses in digital mammograms is a challenging task and a major step in the development of breast cancer CAD systems. In this study, we introduce a new method for automatic detection of suspicious mass candidate (SMC) regions in a mammogram. Methods: Mammography is widely used for the early...

Text and Picture Segmentation by the Distribution Analysis of Wavelet

Statistical classi cation is an important topic in image processing. Classi cation helps to interpret images, and it can be incorporated into other image processing algorithms, e.g., image compression [1], to improve performance. A particularly interesting type of classi cation is the segmentation of pictures and text. By pictures, we mean continuous-tone images such as photographs. By text, we...

Speckle Reduction in Synthetic Aperture Radar Images in Wavelet Domain Exploiting Intra-scale and Inter-scale Dependencies

Synthetic Aperture Radar (SAR) images are inherently affected by a multiplicative noise-like phenomenon called speckle, which is indeed the nature of all coherent systems. Speckle decreases the performance of almost all the information extraction methods such as classification, segmentation, and change detection, therefore speckle must be suppressed. Despeckling can be applied by the multilooki...

آشکارسازی و تعیین مکان متون فارسی - عربی در تصاویر ویدیویی

Video text detection plays an important role in applications such as semantic-based video analysis, text information retrieval, archiving and so on. In this paper, we propose a Farsi/Arabic text detection approach. First, with an appropriate edge detector, edges are extracted and then by using edges cross ponts, artificial corners are extracted. Artificial corner histogram analysis is done for ...
