Abstract: Techniques are generally described to determine whether a JPEG image has undergone two compressions. Probabilities can be computed for the first digits of quantized DCT (discrete cosine transform) coefficients from a set of AC (alternate current) modes to detect or determine whether the JPEG image has undergone two compressions. The set of AC modes may include a predetermined number of distinguishable AC modes where a distinguishable AC mode may be an AC mode in which a second quantization step (QS2) is not an integer multiple of the first quantization step (QS1). Classifiers may be created during a training process, and later may be used to assist in determining whether a suspect JPEG image has undergone two compressions. When the classifiers support a multi-classification system, described detection techniques may also be arranged to determine a primary quality factor for the double compressed JPEG image.
Abstract translation: 通常描述技术来确定JPEG图像是否经历了两次压缩。 可以从一组AC（交替电流）模式的量化DCT（离散余弦变换）系数的第一位计算概率，以检测或确定JPEG图像是否经历了两次压缩。 AC模式的集合可以包括预定数量的可区分AC模式，其中可区分AC模式可以是其中第二量化步长（QS2）不是第一量化步长（QS1）的整数倍的AC模式。 可以在训练过程中创建分类器，并且稍后可以用来帮助确定可疑JPEG图像是否经历了两次压缩。 当分类器支持多分类系统时，还可以安排所描述的检测技术来确定双压缩JPEG图像的主要品质因子。

Abstract: Techniques described herein are generally related to steganalysis of suspect media. Steganalysis techniques may include receiving instances of suspect media as input for steganalytic processing. A first set of quantized blocks of data elements may be identified within the media, with this first set of blocks being eligible to be embedded with steganographic data. A second set of quantized blocks of data elements may be identified within the media, with this second set of blocks being ineligible to be embedded with steganographic data. The steganalysis techniques may requantize the first and second blocks. In turn, these techniques may compare statistics resulting from requantizing the first block with statistics resulting from requantizing the second block. The steganalysis techniques may then assess whether the first block of data elements is embedded with steganographic features based on how the statistics of the second blocks compare with the statistics of the first blocks.

Abstract: This utility model released one kind of multifunctional flexibly transformable cup, comprising one internally cut-through transformable cup and a nested bottom plug that is sealed and clamped with the transformable cup body. The above-mentioned transformable cup is comprised of a foldable enclosure and pin that are successively cut-through and flexibly and tightly connected. The aforesaid seal clamp for embedded bottom plug is located at the junction between the foldable enclosure and pin. When the multifunctional flexibly transformable cup of the utility model is in use, the folding enclosure body can be overturned freely, and the whole body is made of food-grade flexible silica gel material, which is safe and reliable and not easy to be broken. It can also be used as the wine cup, bottle stopper and the bottleneck inserted into the wine bottle that can be directly used for drainage of fluid, with complete functions.

Abstract: Various innovations in media encoding are presented herein. In particular, the innovations can reduce the computational complexity of encoding by selectively skipping certain evaluation stages during encoding. For example, based on analysis of decisions made earlier in encoding or based on analysis of media to be encoded, an encoder can selectively skip evaluation of certain coding tools (such as residual coding or rate-distortion-optimized quantization), skip evaluation of certain values for parameters or settings (such as candidate unit sizes or transform sizes, or candidate partition patterns for motion compensation), and/or skip evaluation of certain coding modes (such as frequency transform skip mode) that are not expected to improve rate-distortion performance during encoding.

Abstract: Innovations in flexible reference picture management are described. For example, a video encoder and video decoder use a global reference picture set (“GRPS”) of reference pictures that remain in memory, and hence are available for use in video encoding/decoding, longer than conventional reference pictures. In particular, reference pictures of the GRPS remain available across random access boundaries. Or, as another example, a video encoder and video decoder clip a reference picture so that useful regions of the reference picture are retained in memory, while unhelpful or redundant regions of the reference picture are discarded. Reference picture clipping can reduce the amount of memory needed to store reference pictures or improve the utilization of available memory by providing better options for motion compensation. Or, as still another example, a video encoder and video decoder filter a reference picture to remove random noise (e.g., capture noise due to camera imperfections during capture).
