This paper describes a view planning of multiple cameras for tracking multiple persons for surveillance purposes. When only a few active cameras are used to cover a wide area, planning their views is an important issue in realizing a competent surveillance system. We develop a multi-start local search (MLS)-based planning method which iteratively selects(More)
A 50-year-old woman had had tenderness of the nail bed of the right thumb for more than 20 years. For the previous 5 or 6 years, she had also had attacks of pain with exposure to cold, and deformity of the right thumb nail plate began to appear. There was red discoloration on the proximal aspect of the nail bed, and a longitudinal fissure on the distal(More)
We show that rational functionalization of the naphthodithiophene core in copolymers based on naphthodithiophene and naphthobisthiadiazole improves the solubility without an alteration of the electronic structure. Surprisingly, the introduction of linear alkyl chains brings about a drastic change in polymer orientation into the face-on motif, which is(More)
We describe a case of a giant epidermal cyst of the buttock that demonstrated a fluid-fluid level on imaging. There have been no previously reported cases of epidermal cysts containing a fluid-fluid level, so our case was considered to be very exceptional. A 39-year-old man had had a slowly enlarging giant subcutaneous mass in the left buttock for more than(More)
This paper deals with a view planning of multiple active cameras for tracking multiple persons for surveillance purposes. We develop algorithms for dynamically planning viewing directions of cameras so that the expected number of tracked persons is maximized, based on a probabilistic model of person motion. Since a naive approach to this planning easily(More)
This article deals with a path-planning problem in tracking humans in order to obtain detailed information about human behavior and characteristics. In our method, path planning is performed based on Kullback-Leibler (KL) divergence between the predicted distribution of all human positions and the intensity of the field of view of the agents. The number of(More)
