Minimal boundary length of a reconstruction

چکیده

If there are multiple images corresponding to one set of line sums, it is interesting to reconstruct an image with a special property. In order to find reconstructions that look rather like a real object, two special properties in particular are often imposed on the reconstructions. The first is connectivity of the points with value one in the picture [6, 8, 28]. The second is hv-convexity : if in each row and each column, the points with value one form one connected block, the image is called hv-convex. The reconstruction of hv-convex images, either connected or not necessarily connected, has been studied extensively [5, 6, 8, 9, 28].

Boundary temperature reconstruction in an inverse heat conduction problem using boundary integral equation method

‎In this paper‎, ‎we consider an inverse boundary value problem for two-dimensional heat equation in an annular domain‎. ‎This problem consists of determining the temperature on the interior boundary curve from the Cauchy data (boundary temperature and heat flux) on the exterior boundary curve‎. ‎To this end‎, ‎the boundary integral equation method is used‎. ‎Since the resulting system of linea...

Is there any Correlation Between Patient Height and Patellar Tendon Length?

 Background: A potential specific problem of patellar tendon graft in ACL reconstruction is the possibility of graft-tunnel mismatch which could be more problematic with anatomic ACL reconstruction where the femoral tunnel is placed low on the lateral wall of the lateral femoral condyle. The occasional occurrence of this mismatch raises the question that whether a correlation exists between pat...

مطالعه نیمه‌کلاسیکی چند رابطه جابه‌جاگری تعمیم‌یافته

  Our aim in this paper is to find the observable effects of the generalized commutators. For this purpose we investigate two problems in quantum mechanics with minimal length procedure. Firstly, we study hydrogen atom energy levels via minimal length uncertainty relation algebra. From comparing our results, with experimental data we estimate an upper limit for minimal length. Secondly, we inve...

A Geochemical Approach to the Palaeo Coastline Reconstruction in southern Khuzestan Plain

Several studies had been tried to illustrate the paleo coastlines of the Persian Gulf during the Holocene. A review of those researches reflects the fact that all of them have stablished their facts based on the sedimentary environment interpretations with no quantitative evidence. Generally, the study area is a changing environment which is a combination of riverine, continental, coastal and e...

Efficient Convex Optimization for Minimal Partition Problems with Volume Constraints

Minimal partition problems describe the task of partitioning a domain into a set of meaningful regions. Two important examples are image segmentation and 3D reconstruction. They can both be formulated as energy minimization problems requiring minimum boundary length or surface area of the regions. This common prior often leads to the removal of thin or elongated structures. Volume constraints i...
