image segmentation using wavelet-domain classification

Image segmentation using wavelet-domain classification

Conference on Mathematical Modeling, Bayesian Estimation, and Inverse Problems

作者： Choi, H Baraniuk, R Rice Univ Dept Elect & Comp Engn Houston TX 77005 USA

ISBN: (纸本)0819433020

We introduce a new image texture segmentation algorithm, HMTseg based on wavelet-domain hidden Markov tree (HMT) models. The HMT model is a tree-structured probabilistic graph that captures the statistical properties of wavelet coefficients. Since the HMT is particularly well suited to images containing singularities (edges and ridges), it provides provides a good classifier for textures. Utilizing the inherent tree structure of the wavelet HMT and its fast training and likelihood computation algorithms, we perform multiscale texture classification at various scales. We then fuse these multiscale classifications using a Bayesian probabilistic graph to obtain a reliable final segmentation. Since HMTseg works on the wavelet transform of the image, it can directly segment wavelet-compressed images, without the need for decompression. We demonstrate the performance of HMTseg with synthetic, aerial photo, and document image segmentations.

OPTIMAL OPENINGS FOR OVERLAPPING SIGNAL AND NOISE GRAINS 5

Optimal openings are considered for extraction of signal from noise in the random binary union-noise model. Disjointness of signal and noise is not assumed, nor are grains within the signal or within the noise assumed to be disjoint. There is a constraint on the overlapping, but this reflects the manner in which binary granular images are derived from gray-scale images of touching objects. The method assumes that the degraded image is segmented by the binary watershed algorithm and that an optimal opening by reconstruction must be found to remove segmented noise grains while passing segmented signal grains.

CONF ON INTELLIGENT ROBOTS AND COMPUTER VISION 10 : algorithms AND TECHNIQUES

作者： WILKINSON, RA National Institute of Standards and Technology (United States)

image segmentation, the partitioning of an image into meaningful parts, is a major concern of any computer vision system. The meaningful parts of a text image are lines of text, words, and characters. In this paper, the segmentation of pages of text into lines of text and lines of text into characters on a parallel machine are examined. Using a parallel machine for text image segmentation allows the use of techniques that are impractical on a serial machine due to the computation time needed. It is possible to use a parallel machine to segment text images of lines using spatial histograms with an accuracy of 97.9% at a speed of 30 milliseconds or less per character. Statistically adaptive rules based on dynamic adaptive sampling are used for line segmentation and also for improved accuracy of character segmentation. The segmentation of lines from a page can also be accomplished using a set of statistically adaptive rules which allow sloped lines of text to be segmented. The use of these statistical rules on a parallel machine increases processing time by no more than 1 millisecond per character. Using statistical rules in combination with knowledge about the printed style increases the segmentation accuracy to 99.2% correct for machine-printed text and 89.6% for hand-printed text.

Scanning count is an efficient way to recognize and count the number of components in a picture . After all points in one line of a target having been scanned, one of the end points in the next line of the target can be determined,then the new line can be scanned . At the sane time , the line of another side is checked to avoid any omission .Of course, this method is easy to detect that one target has been scanned over. Each point in a target is visited approximate two times . And break points can be jumped over automatically . The number and each area of targets are then calculated . Compared with the conventional algorithms, the new one is simple and fast, and is practicable in personal computers.

In this work, we present a technique which suggests the use of symmetry to reduce the redundancy in images. A symmetry-based image segmentation and coding scheme is described. A segmentation technique is analyzed, and applied on natural images, performing their efficient partition. In order to find symmetries in regions of any shape, the concept of axes of symmetry is generalized to skeletons of symmetry, dividing the regions into two symmetric subparts by the introduction of the Medial Axis Transformation of the regions. Each subpart of the regions is then linearly predicted with respect to the skeletons. An efficient coding strategy specifying the shape and the luminance of the regions is described. Results on natural images show that the described technique outperforms the more classical second generation image coding methods in terms of visual quality.

Individual cluster validation has not received as much attention as partition validation. This paper presents two measures for evaluating individual clusters in a fuzzy partition. They both account for properties of the fuzzy memberships as well as the structure of the data. The first measure is a ratio between compactness and separation of the fuzzy clusters; the second is based on counting a contradiction between properties of the fuzzy memberships and the stucture of the data. These two measures are applied and compared in evaluating fuzzy clusters generated by the fuzzy c-means algorithm for segmentation of magnetic resonance images of the brain.

This paper proposes a massively parallel line feature extraction technique for 2D images. This new scheme uses a modified Hough transform implemented in a massively parallel fashion to extract the line features in an input image. The algorithm is based on the recursive decomposition technique. A parallel Hough transform detects line segments in the subimages of the input image. A bottom up approach then merges these line segments into longer lines. A pointerless tree structure is utilized to store feature information at various levels of the merging process. The line segment merging process is equivalent to climbing the tree representing the line features in the entire image. Techniques for line feature merging and balancing of features, tradeoffs between determination of line properties and computation, and algorithmic complexity are addressed in detail.

Optical coherence tomography angiography (OCTA) is a novel noninvasive imaging modality for visualization of retinal blood flow in the human retina. Using specific OCTA imaging biomarkers for the identification of pathologies, automated image segmentations of the blood vessels can improve subsequent analysis and diagnosis. We present a novel segmentation method for vessel density identification based on frequency representations of the image, in particular, using so-called Gabor filter banks. The algorithm is evaluated qualitatively and quantitatively on an OCTA image in-house data set from 10 eyes acquired by a Cirrus HD-OCT device. Qualitatively, the segmentation outcomes received very good visual evaluation feedback by experts. Quantitatively, we compared the resulting vessel density values with automated in-built values provided by the device. The results underline the visual evaluation. For the evaluation of the FAZ identification substep, manual annotations of 2 expert graders were used, showing that our results coincide well in visual and quantitative manners. Lastly, we suggest the computation of adaptive local vessel density maps that allow straightforward analysis of retinal blood flow in a local manner.

This paper presents an automatic method for segmentation of Multiple Sclerosis (MS) in Magnetic Resonance images (MRI) of the brain. The approach is based on similarities between multi-channel patches (T1, T2 and FLAIR). An MS lesion patch database is built using training images for which the label maps are known. For each patch in the testing image, k similar patches are retrieved from the database. The matching labels for these k patches are then combined to produce an initial segmentation map for the test case. Finally a novel iterative patch-based label refinement process based on the initial segmentation map is performed to ensure spatial consistency of the detected lesions. A leave-one-out evaluation is done for each testing image in the MS lesion segmentation challenge of MICCAI 2008. Results are shown to compete with the state-of-the-art methods on the MICCAI 2008 challenge.

Computation of ventricular volume and the diagnostic quantities like ejection-fraction ratio, heart output, mass, etc. requires detection of myocardial boundaries. The problem of segmenting an image into separate regions is one of the most significant problems in vision. Terzopoulos et al., have proposed an approach to detect the contour regions of complex shapes, assuming a user selected an initial contour not very far from the desired solution. We propose an optimal dynamic programming (DP) based method to detect contours. It is exact and not iterative. We first consider a list of uncertainty for each point selected by the user, wherein the point is allowed to move. Then, a search window is created from two consecutive lists. We then apply a dynamic programming (DP) algorithm to obtain the optimal contour passing through these lists of uncertainty, optimally utilizing the given information. For tracking, the final contour obtained at one frame is sampled and used as initial points for the next frame. Then, the same DP process is applied. We have demonstrated the algorithms on natural objects in a large spectrum of applications, including interactive segmentation of the regions of interest in medical images.
