Microarray technology is considered to be one of the major breakthroughs in bioinformatics for profiling gene-expressions of thousands of genes, simultaneously. Analysis of a microarray image plays an important role in the accurate depiction of gene-expression. Segmentation, the process of separating the foreground from the background, of a microarray image, is one of the key issues in microarray image analysis. Level sets have tremendous potential in the segmentation of images. In this paper, a new approach for segmentation of the microarray images is proposed. In this work, Chan-Vese approximation of the Mumford-Shah model and the level set method are employed for image segmentation. Illustrative examples of the proposed method are presented highlighting its effectiveness.
微阵列技术被认为是生物信息学领域的重大突破之一,它能够同时对数千个基因的表达进行分析。微阵列图像分析在准确描述基因表达方面起着重要作用。微阵列图像的分割,即将前景与背景分离的过程,是微阵列图像分析中的关键问题之一。水平集在图像分割方面具有巨大潜力。本文提出了一种微阵列图像分割的新方法。在这项工作中,采用了Mumford-Shah模型的Chan-Vese近似和水平集方法进行图像分割。给出了该方法的示例,突出了其有效性。
