The 2012 Computational Optical Sensing and Imaging (COSI) conference of the Optical Society of America was one of six colocated meetings composing the Imaging and Applied Optics Congress held in Monterey, California, 24–28 June. COSI, together with the Imaging Systems and Applications, Optical Sensors, Applied Industrial Optics, and Optical Remote Sensing of the Environment conferences, brought together a diverse group of scientists and engineers sharing a common interest in measuring and processing of information carried by optical fields. This special feature includes several papers based on presentations given at the 2012 COSI conference as well as independent contributions, which together highlight several important trends.

- • Measuring projections or transforms of the underlying signal to avoid the limitations of conventional approaches—such as in synthetic aperture imaging, which avoids the resolution limit associated with the size of the physical receiver aperture, or holography and correlography methods that entirely eliminate the lens system.
- • Use of a priori knowledge regarding signal properties to achieve improved sensing performance and enable novel sensing methods, such as in the recent developments in compressed sensing.
- • Efficient methods for obtaining information about higher-dimensional optical fields, for example, 3D and light-field sensing.
- • Advanced signal recovery methods for inferring the underlying signal from measurements acquired in complicated transform domains.
- • Use of auxiliary measurements (i.e., measurement diversity) to overcome a variety of performance-limiting signal degradations, such as motion blur, wavefront error, and detector undersampling.
