The watershed transform is a popular segmentation method coming from the field of mathematical morphology. In order to solve the over-segmentation of watershed algorithm's applied to medical images, we first transform the original image into a morphological gradient image by using morphology methods and treat it with an opening-closing filter bank to get a(More)
In this paper, we propose a new filtration method, called Transformation-based Database Filtration method (TDF), to screen out those data sequences of a DNA sequence database which cannot satisfy a given query sequence. Our proposed method consists of two phases. First, we divide each data sequence into several windows (blocks), each of which is transformed(More)
AIM To construct a system for selecting reference genes (RGs) and to select the most optimal RGs for gene expression studies in nasopharyngeal carcinoma (NPC). METHODS The total RNAs from 20 NPC samples were each labeled with Cy5-dUTP. To create a common control, the total RNA from 15 nasopharyngeal phlogistic (NP) tissues was mixed and labeled via(More)
Previous studies showed that type 2 diabetes mellitus (T2DM) is linked to increased risk of developing colon cancer. Insulin and insulin-like growth factor 1 (IGF-1) are increased in patients with T2DM. The increased insulin and IGF-1 may be responsible for the developing of colon cancer. In this study, we investigated the effects and mechanisms of insulin(More)
We present an improved texture synthesis algorithm over arbitrary surfaces in this paper. The algorithm adopt the searching strategy of restriction degree to compute the texture coordinates of each triangular patch. It reduces the restrictive conditions as searching for the best matching patches and debases the complexity of the algorithm at the same time.(More)
