Abstract Food safety is a major issue related to the vital interests of people. In recent years, food incidents have emerged in an endless stream China. However, existing traceability methods lack data sharing, which makes it difficult conduct unified supervision on safety. view problems current method, this paper introduces blockchain technology field, selects milk as object paper, analyzes whole process supply chain, designs overall framework scheme according demand analysis and design...

In this paper, we propose a novel spatial error concealment algorithm based on adaptive linear predictor. The predictor automatically tunes its order and support shape according to local contexts. optimal is determined using Bayesian Index Criterion (BIC). order-adaptive able recover more important features or structures. Simulation results show that compared the state-of-the-art algorithms, proposed method gives better reconstruction performance in terms of objective subjective evaluations.

In this paper, a novel patch-wise saliency detection algorithm is proposed based on principal component analysis (PCA). As powerful statistical procedure in data analysis, PCA fully exploited to convert color space and produce compact patch representation. Specifically, images are first converted linearly uncorrelated channels divided into non-overlapped patches. Then the patches represented by coefficients of components using analysis. Based representation patches, two types distinctiveness...

This paper presents an edge-directed, noniterative image interpolation algorithm. In the proposed algorithm, gradient directions are explicitly estimated with a statistical-based approach. The local dominant obtained by using principal components analysis (PCA) on four nearest gradients. angles of whole plane divided into parts, and each direction falls one part. Then we implement one-dimention (1-D) cubic convolution perpendicular to direction. Compared state of-the-art methods, simulation...

High Efficiency Video Coding (HEVC) is a promising standard for video compression. In intra prediction, HEVC achieves better compression performance by adopting numbers of new tools such as more flexible partitioning structure and up to 35 prediction modes. However, these also lead great increase in computational complexity. this paper, fast mode CU depth decision algorithm based on characteristics coding bits put forward speed the process coding. The number difference (IPMC) between most...

The latest high efficiency video coding (HEVC) standard significantly increases the encoding complexity for improving its efficiency. Due to limited computational capability of handheld devices, constrained has drawn great attention in recent years. A control algorithm based on adaptive mode selection is proposed interframe HEVC. Considering direct proportionality between time and complexity, measured terms time. First, mapped a target prediction modes. Then, an decision process....

Unlabeled data can be easily collected and help to exploit the correlations among different modalities. Existing works tried explore label information contained in unlabeled data, however most of them suffer from difficulties separating samples categories have great interference. This paper proposes a novel method named semi-supervised cross-modal hashing based on prediction distance preserving(SS-LPDP). First, we use deep neural networks extract feature labeled modalities get distribution...

This paper describes a flexible transducer for neural science based on polyimide. It can stimulate the neuron by electricity or light, record electrical signal, and detect tissue temperature to avoid heat damage of cortex μLED. Furthermore, electrode modified platinum (Pt) black has an excellent stimulation recording ability. The capability interface was demonstrated in vitro. A low impedance (7.2 kΩ) been achieved with 80-μm-diameter site at 1 kHz. With help sensor, 2.4 V-3.0 V found as...
