We present a method that partitions a single image into two layers, requiring that one layer has similar properties in terms of pixel colour variation to a provided template patch. First, the paper provides a new view on defining a similarity function for a pixel with its small neighbourhood to be part of the texture described by the template patch. This results in better description of pixels ...

In the first part of this report, the performance of four state of art detectors is given, both in Repeatability Check and Image Retrieval. In the Repeatabiilty and Matching test,MSER works best in the viewpoint and illunimation change, while SIFT,SURF and Hessian Affine are proved to be robust to the scale changes, image Blur and JEPG compression.On the other hand,in the Image Retrieval Test,S...

According to SIFT algorithm does not have the property of affine invariance, and the high complexity of time and space, it is difficult to apply to real-time image processing for batch image sequence, so an improved SIFT feature extraction algorithm was proposed in this paper. Firstly, the MSER algorithm detected the maximally stable extremely regions instead of the DOG operator detected extrem...

Scene text recognition brings various new challenges occurs in recent years. Detecting and recognizing text in scenes entails some of the equivalent problems as document processing, but there are also numerous novel problems to face for recognizing text in natural scene images. Recent research in these regions has exposed several promise but present is motionless much effort to be entire in the...

We show how to exploit temporal and spatial coherence to achieve efficient and effective text detection and decoding for a sensor suite moving through an environment in which text occurs at a variety of locations, scales and orientations with respect to the observer. Our method uses simultaneous localization and mapping (SLAM) to extract planar “tiles” representing scene surfaces. It then fuses...

The image content detectability and image structure preservation are closely related concepts with undeniable role in image quality assessment. However, the most attention of image quality studies has been paid to image structure evaluation, few of them focused on image content detectability. Examining the image structure was firstly introduced and assessed in Structural SIMilarity (SSIM) measu...

Image alignment is an essential task in many applications of hyperspectral remote sensing images. Before any processing, the images must be registered. The Maximally Stable Extremal Regions (MSER) a feature detection algorithm that extracts regions by thresholding image at different grey levels. These extremal are invariant to transformations making them ideal for registration. Scale-Invariant ...

Text-detection is a well-established topic within the document recognition domain, but detecting text in natural scenes has proved to be considerably harder due to the large variability of text appearances, and due to dominating clutter. In this paper, we begin with a practical model for text appearance and use it to motivate the design of a text detection system consisting of two stages: a hyp...
