IBCIS: intelligent blood cell identification system

The analysis of blood cells in microscope images can provide useful information concerning the health of patients. There are three major blood cell types, namely, erythrocytes （red）, leukocytes （white）, and platelets. Manual classification is time consuming and suscep- tible to error due to the different morphological features of the cells. This paper presents an intelligent system that simulates a human visual inspection and classification of the three blood cell types, The proposed system comprises two phases： The image preprocessing phase where blood cell features are extracted via global pattern averaging, and the neural network arbitration phase where training is the first and then classification is carried out. Experimental results suggest that the proposed method performs well in identifying blood cell types regardless of their irregular shapes, sizes and orientation, thus providing a fast, simple and efficient rotational and scale invariant blood cell identification system which can be used in automating laboratory reporting.

UCIMssp:Ubiquitous Computing Identification Mechanism Based on SPKI/SDSI and P2P

Ubiquitous computing systems typically have lots of security problems in the area of identification supply by means of classical Public Key Infrastructure （PKI） methods. The limited computing resources, the disconnection network, the classification requirements of identification, the requirement of trust transfer and cross identification, the bidirectional identification, the security delegation and the privacy protection etc are all these unsolved problems. In this paper, UCIMssp, a new novel ubiquitous computing identification mechanism based on SPKI/SDSI and Peer-to-Peer （P2P） is presented. SPKI- based authorization is exploited in UCIMssp to solve the above problems in the smalbscale ubiquitous computing environment. The DHT and flooding technology of P2P overlay network over the Intemet is expanded to solve the routing search in the large-scale ubiquitous computing environment. The architecture of ubiquitous computing environment, the validation of identification requisition, the identification authorization processes and the identification supply processes etc of UCIMssp are described in the paper. The performance analysis shows that UCIMssp is a suitable security solution used in the large-scale ubiquitous computing environment.
