Sequential Estimation of Boundaries Intexture Images

چکیده
In this paper we describe a metho.d. for estimating boundaries between percep~ually d1stmct regions in an image. The method 1S a two step procedure which first identifies image regions ~hich exhibit uniformity. Boundaries between umform regions are approximated by a complete cubic spline function and the linear recursive filter is used to estimate the values of the function at the knots. Boundaries 3.re assumed to be smooth; however. abrupt changes in boundary loc~tion may infrequently occur. In th~se ~xceptlOn~1 cases flexibility of boundary approx1matlOn 1S ach1eved by adding additional knots at the positions where abrupt changes occur.

In this paper, a new method for mineral boundary detection is proposed using a model prepared in ArcGIS ModelBuilder tool. Required data for this method are gray scale images taken from petrographic thin sections. The images are captured in 19 numbers through 90° polarizers and lambda plate rotation with 5° intervals while the microscope table is fixed. Mineral boundaries are detected using the...

Introduction: This study presents a computerized analyzing method for detection of instantaneous changes of far and near walls of the common carotid artery in sequential ultrasound images by applying the maximum gradient algorithm. Maximum gradient was modified and some characteristics were added from the dynamic programming algorithm for our applications. Methods: The algorithm was evaluat...
متن کاملExtraction of Color Region Boundaries
The literature on region analysis is dominated by algorithms and applications for binary images. In contrast, region analysis of color images is a relatively unexplored field. This paper presents some new research that strengthens the notational support for boundary encoding of color image regions, offers a sequential algorithm for extracting color region boundaries and outlines a VLSI architec...
متن کاملA Statistical Method for Sequential Images – Based Process Monitoring
Today, with the growth of technology, monitoring processes by the use of video and satellite sensors have been more expanded, due to their rich and valuable information. Recently, some researchers have used sequential images for image defect detection because a single image is not sufficient for process monitoring. In this paper, by adding the time dimension to the image-based process monitorin...
متن کاملSequential estimation of linear combinations of the location and scale parameters in negative exponential distribution
Sequential estimation is used where the total sample size is not fix and the problem cannot solve with this fixed sample size. Sequentially estimating the mean in an exponential distribution (one and two parameter), is an important problem which has attracted attentions from authors over the years. These largely addressed an exponential distribution involving a single or two parameters. In t...
