independent of the image sensor's pixel size. This super-resolution is achieved by integrating a nano-aperture patterned in the first metal layer within the pixel using a standard CMOS process. The image sensor's focal plane is scanned with a sub-micron step to obtain the super-resolution ...
Super Resolution 小总结 不知道哪辈子写的垃圾玩意,别看 SRCNN SRCNN算是鼻祖吧,实现的过程很简单,就是用了三个卷积层: Low-resolution图片在最开始先用bicubic插值将lr图放大成目标尺寸,然后作为输入有一个patch extraction and representation得到LR特征图1,再有一个非线性映射(Non-linear mapping)得到特征图n2,最...
δ < σ. Second, the spatial resolution of the imaging system must be limited by the pixel size. This is true if the higher spatial frequency component of the optical field in the object plane is both smaller than the imaging system spatial frequency cut-off and larger than the sensor ...
sub-pixel请参考: Real-Time Single Image and Video Super-Resolution Using an Efficient Sub-Pixel Convolutional Neural Network 可以减少计算时间和轻量化网络模型。 4. 如何实现感知损失? 使用预训练的VGG-net提取图片特征。具体参考李飞飞2016年论文。Perceptual Losses for Real-Time Style Transfer and Super-...

Based on image encoding in a serial-temporal format, optical time-stretch imaging entails a stringent requirement of state-of-the-art fast data acquisition unit in order to preserve high image resolution at an ultrahigh frame rate — hampering the widesp
AV1的Up Scaler(Super-resolution)过程介绍 AV1的Super-resolution(superres)技术允许encoder对任意一帧输入图像的水平分辨率降低至多1/2(downsampling)。这种动态分辨率改变能力为Codec的压缩能力和质量开辟了一个新的方向,这是之前任何带有硬件解码支持的Codec标准都没有提出过的一项新的编解码技术。
make print quality, use the Super Resolution feature in Adobe photoshop lightroom. Super Resolution creates a single image with two times the linear resolution. That means the enhanced image will have twice the width and twice the height of the original image, or four times the total pixel ...
Hardware Design The high resolution camera used had a 20.1M P , 1/2.4 format CMOS image sensor supporting 5344(H) × 3752(V ) frame capture, 1.12µm pixel size, and lens focal length of f = 4.418mm (F/1.94), providing a 68.2◦ ×50.9◦ field of view (FOV). The camera ...
A superresolution imaging approach that localizes very small targets, such as red blood cells or droplets of injected photoacoustic dye, has significantly improved spatial resolution in various biological and medical imaging modalities. However, this superior spatial resolution is achieved by sacrificing ...
