The Spatial image transformation core is a signal processing accelerator designed for single or multi-channel image manipulations based on matrix multiplication. The core is packaged as an AXI-Stream compatible accelerator, which features a bi-cubic interpolation for reconstruction and parallel access to...

spatial transformer 可以包括:平移、旋转、放缩等操作。 在数学上的名称有: affine transformasion ,另外还有:projective transformation、 piece-wise affine、 thin plate spline等。 实施方法: 列举文中的二维的例子: 对于二维的图片识别中,如果图片是旋转的怎么办?被平移怎么办?(通常做法就是不管输入如何,我就统统...

Whatisimageenhancement?采用一系列技术去改善图象的视觉效果,或将图象转换成一种更适合于人或机器进行分析处理的形式。图象增强不以图象保真为准则,而是有选择地突出某些对人或机器分析有意义的信息,抑制无用信息,提高图象的使用价值。Example:Example: Whatisagoodimage?For Acertainamountoftrial(试)anderror...
This transformation uses as its logical basis the assumption that the visual system can be modelled as a logarithmic amplifier which is sensitive to modulation in proportion to the logarithm of the modulation. Accordingly, they transformed the modulation axis into “just noticeable differences” or “...
