An_Improved_of_spiht_Algorithm_Based_on_Variable_T
- 針對傳統小波變換過程復雜的缺點和SPIHT算法編碼過程重復運算、存儲量大的問題,首先分析了小波基和小波分解層數的選擇,然后提出了一種新的可變閾值的SPIHT算法,該算法利用可變閾值對SPIHT算法中不重要像素列表(LIP)和不重要系數列表(LIS)進行分類得到一種更有效的編碼算法.仿真結果表明,該算法的壓縮整體性能要好于SPIHT算法.-Wavelet transform for the traditional complex process shortcomings and repeat th

- In an image edge is more important to interpolate the missing pixel values. In similarity algorithm edge is detected using the unified high frequency map. Based on this the missing green pixels are interpolated by taking the average of surroundin
Android屏幕适配全攻略(最权威的官方适配指导)
- 重要概念 什么是屏幕尺寸、屏幕分辨率、屏幕像素密度? 什么是dp、dip、dpi、sp、px?他们之间的关系是什么? 什么是mdpi、hdpi、xdpi、xxdpi?如何计算和区分? 在下面的内容中我们将介绍这些概念。 屏幕尺寸 屏幕尺寸指屏幕的对角线的长度,单位是英寸,1英寸=2.54厘米 比如常见的屏幕尺寸有2.4、2.8、3.5、3.7、4.2、5.0、5.5、6.0等 屏幕分辨率 屏幕分辨率是指在横纵向上的像素点数,单位是px,1px=1个像素点。一般以纵向像素横向
Accurate Segmentation of Cervical Cytoplasm and Nuclei Based on Multiscale Convolutional Network and Graph Partitioning
- In this paper, a multiscale convolutional network (MSCN) and graph-partitioning-based method is proposed for accurate segmentation of cervical cytoplasm and nuclei. Specifically, deep learning via the MSCN is explored to extract scale invariant f
