Coded Photography

Category	Feature	Related works	Advantages	Disadvantages
Illumination coding	Fourier ptychography	Zheng et al^[12]Tian et al^[13]Zhang et al^[14]	High throughput intensity and phase imaging	Sacrifice time resolution for high image quality
Optical pathcoding	Coded aperture	Levin et al^[15]Brady et al^[16]Lin et al^[17]	Multidimensional information recovery from single image with theoretical high coded efficiency	Reduced image quality compare with specific instrument
	Scattering coding	Katz et al^[18]Popoff et al^[19]Wang et al^[20]	Higher coded efficiency with resolution beyond diffraction limit	Reconstruction is unstable and lack of theoretical exploration
	Light field photography	Park et al^[21]Levoy et al^[22]	3D scene reconstruction and rendering from a single image	Limited spatial resolution
Sensor coding	Coded sensor	Raskar et al^[23]Gu et al^[24]Wan et al^[25]	Can solve the motion blur problem, achieve high dynamic range imaging	Low frame rate, limited spatial resolution
Sensor coding	Dynamicvision sensor	Harris et al^[26]Lichtsteiner et al^[27]	High pixel bandwidth, wide dynamic range, low latency	Unable to read depth, edge, contrast, color
