Malignant tumors appear to own the ability to recruit normal tissue cells that contribute to the tumorigenesis process by creating the “tumor microenvironment”. MMPs, is one of the most significant family of proteinases that are related to tumor microenvironment. Recent understanding of MMPs has recognized its role as modulators in tumor microenvironment; however, the current strategies for in vivo...
This paper proposes a method based on the bag-of-words (BoW) and the softmax regression for microscopic image classification. Essentially, the locality-constrained linear coding (LLC) is adopted for local feature encoding. Compared with the traditionally adopted vector quantization (VQ) in the BoW framework, the LLC encodes local structures of microscopic images with lower quantization errors and...
The purpose of research on image quality assessment (IQA) is to find proper methods to measure the quality of images. The subjective evaluation score by HVS is usually used as a standard to be compared with. So, the more similar the measuring process is to HVS, the better the result should be. Motivated by this idea, contourlet transform and singular value decomposition are used in this article to...
Biological features, such as, genes, transcription factor binding sites, SNPs, etc., are usually denoted with genome-based coordinates as the genomic features. While genome-based representation is usually very effective, it can be tedious to examine the distribution of RNA-related genomic features on RNA transcripts with existing tools due to the conversion and comparison between genome-based coordinates...
For the visual servo system, especially with the low-cost camera, there are problems on time delay which is caused by the difference between image processing period and robot control period. In this paper, the time delay in image processing is mainly discussed as the sampling period of the image processing is much longer than that of robot control. A scheme by the robot's pose and estimated image...
In this paper, we focus on the problem of complicated scene retrieval and give two proposals to improve accuracy of the recent image search system based on bag-of-features: block voting mechanism and weak feature selection. Both the methods aim to reduce effects of incorrect matching between descriptors. Block voting mechanism separates query and database images into blocks when computing image matching...
