因为在上游的时候 image size(图片尺寸)比较小,然后我们知道大 Kernel 的话,它的 padding 是很大的,padding 会泄露很多绝对位置信息。比如,在上游训练中你要分类一个苹果,假如说苹果出现在左上角,那么如果你不泄露绝对位置信息,那么它就会严格根据苹果的 appearance(外观)来进行分类,那么在你测试的时候把苹果移到...
其实我们这项研究,其实首要目的并不是为了找一个在某项任务上最优的一个 Kernel size,而是指出一个方向——你想让网络达到更大的感受野,实现更好的性能,那么你的 Kernel size 的总体趋势是要越变越大,主要是一个趋势的问题。 至于在现有的数据集、现有的 training setting(训练设置)下,哪个 size 最好,这个是...
(9.40). The function parameters are the image, the location of the tracking region, the region size, and the kernel size h. The function in Code 9.2 uses as features the color components Cb and Cr defined in Chapter 13, Appendix 4. Thus, the entries yu correspond to 2D color features,...

The matting processing is performed using the selected kernel size to provide an alpha matte that distinguishes a foreground portion from a background portion in the unknown region. Further, in some implementations, a trimap of the image may be segmented and matting processing may be performed on...
Full size image While conventional MKL frameworks use SVM for classification, in NGMKL, we use softmax for classification. Let \(\text {z}^{l} \in {\mathbb {R}}^c\), where c is the number of classes. The softmax classifier assigns c probabilities to the data as follows: $$\begin...

Further, in some implementations, a trimap of the image may be segmented and matting processing may be performed on each segment using a kernel size appropriate for that segment.doi:US8625888 B2Jian SunKaiming HeUS
Moreover, the kernel with fixed size fails to capture the features of different scales and properties. In this paper, we propose a deep learning method for processing X-ray chest images to assist COVID-19 detection. Our method extracts features by introducing attention and variable kernel size....
