“…In this paper, unlike conventional error control coding techniques [11], we choose to integrate multiple description coding into compressed sensing to make error resilient coding possible. We treat the CS coefficients as the input data, and transmit two descriptions over two independent channels with loss probability p e1 and p e2 with the subscript e denoting the error induced during transmission.…”

Compressed sensing (CS), due to its superior performances that very few amounts of coefficients are capable of reconstructing the image with reasonable quality, is an effective means in data compression in recent years. For the transmission of image compressed with CS, due to the channel errors that may be experienced, data protection would be required. We employ multiple description coding (MDC) for protecting color images with compressed sensing. With MDC, compressed information can be divided into different chunks at the encoder, and all the chunks can be transmitted over multiple independent channels to alleviate the influences caused by channel errors. At the decoder, the possibly corrupted chunks are assembled together, and MDC can be applied to reconstruct the image. With our algorithm, simulation results presented the error resilient capability and improved quality of color images.

“…Benefiting from exploring the EXIF header information, EXIF has been adopted in various applications by researchers, such as image retrieval [131][132][133][134][135], simple zoomlens digital camera calibration [136], and digital watermarking [137,138]. In [131], In [137,138], the EXIF information is considered as watermarks to enhance the image copyright protection. However, their work does not exploit the information provided by EXIF headers for watermarking.…”
