Advances in graphics and machine learning have led to the general availability of easy-to-use tools for modifying and synthesizing media. The proliferation of these tools threatens to cast doubt on the veracity of all media. One approach to thwarting

The popularization of video capture devices has created strong storage demand for encoded videos. Approximate storage can ease this demand by enabling denser storage at the expense of occasional errors. Unfortunately, even minor storage errors, such

This is a somewhat unusual paper. It combines some history of the author's personal experiences with Prof. Sanjit Mitra with a couple of examples of the author's work, in which the author feels that Prof. Mitra's work and approaches towards research

This paper proposes tailoring image encoding for an approximate storage substrate. We demonstrate that indiscriminately storing encoded images in approximate memory generates unacceptable and uncontrollable quality degradation. The key finding is tha

The impact of a technical article may have as much to do with how well it is presented as with the engineering or scientific significance of the work. A well-written article is easier to understand and easier to remember; the more readers that rememb

This article proposes a multimedia content protection system in which all copies of a protected object are identically watermarked, but each user has a distinct secret detection key that differs from the secret embedding key. An attacker with access

This paper presents an overview of the transform and quantization designs in H.264. Unlike the popular 8/spl times/8 discrete cosine transform used in previous standards, the 4/spl times/4 transforms in H.264 can be computed exactly in integer arithm

Watermarking has become a technology of choice for a broad range of multimedia copyright protection applications. Watermarks have also been used to embed format-independent metadata in audio/video signals in a way that is robust to common editing. In

Summary form only given. High-resolution color video (in 4:4:4 format) is becoming increasingly important for screen content and graphics. We have developed a frame packing arrangement (FPA) scheme that enables transmission of 4:4:4 luma-chroma (YUV
