In this paper, a novel manifold learning algorithm termed orthogonal nearest neighbor feature space embedding (ONNFSE) is proposed to eliminate three drawbacks of the nearest feature space embedding (NFSE) approach. The first one is an extrapolation error, a feature line passes through two far neighbor points is selected for scatter matrix calculating when the distance of a specified point to this...
Brightness obviously affects the pixel value of an image sensor. Image identification from a traditional sensor may generate a bias and surveillance misunderstandings because of weather. The proposed intelligent image sensor integrates an optoelectronic converting circuit and an embedded system and can convert the brightness to an analog voltage. From the voltage value, we can establish a contrast...
In using ultrasound echo strain to estimate temperature for monitoring HIFU thermal therapy, block matching algorithms are used to estimate the displacement over two image frames. However, due to the image distortion and artifacts over frames, the displacement will be estimated with outliers which will seriously bias echo strain estimation. This paper introduces a novel model-based algorithm to constrain...
Brightness obviously affects the pixel value of an image sensor. Image identification from a traditional sensor may generate a bias and surveillant misunderstandings because of weather. The purpose of the research is to develop an intelligent image sensor with mobile communication function applied to Vehicle surveillance system. The proposed intelligent image sensor integrates an optoelectronic converting...
