Embedded machine vision algorithm development platform is of great significance. Based on the elaboration of visual communication design, this paper further details the design of fractal visual art graphics based on computer-aided algorithms to design edge detection schemes, where edges represent sudden changes in the signal and are able to characterize the rich information of an image. In response to the problems of poor robustness and difficult parameter selection of the currently widely used edge detection algorithms, the platform encapsulates joint edge detection graphic components in a higher-order processing library to achieve the requirements of high-precision detection and to realise enhanced edge detection effects. Finally, the experimental analysis shows that the proposed algorithm has a more accurate detection effect and can meet the user's high-precision detection requirements. [ABSTRACT FROM AUTHOR]

Summary: Autonomous photo‐rechargeable electronic energy storage device has become a new type of solution to the problems of renewable energy fluctuations and storage. The combination of light conversion equipment and energy storage equipment improves the packaging efficiency of the equipment, however how to explore a type of electrode materials for energy collection and storage become a real challenging issue. Here, we try to explore the GeSe nanoparticles as the potential idea electrode for the integrated photo‐rechargeable battery. On the one hand, GeSe nanoparticle electrode shows good Li+ storage performances. At the current density of 0.2 A g−1, its reversible capacity is 670 mAh g−1 after 100 cycles. On the other hand, during the photo‐voltaic measurement, GeSe electrodes could generate a photocurrent that increases by 8 uA/cm2 under the visible light irradiation in aqueous electrolyte. When LiClO4 in polycarbonate solvent is used as the electrolyte, the electrons move in the reverse direction from the GeSe electrode, form reverse current, reduce Li+ to lithium metal, and finally store light energy into chemical energy in a short time. Considering its presenting behaviors in Li+ storage and photon harvesting, our research proposed the possibility for the application of GeSe materials in the integrated photo‐rechargeable batteries.

Sodium molybdate (Na−Mo−O) wrapped by graphene oxide (GO) composites have been prepared via a simple in‐situ precipitation method at room temperature. The composites are mainly constructed with one dimension (1D) ultra‐long sodium molybdate nanorods, which are wrapped by the flexible GO. The introduction of GO is expected to not merely provide more active sites for lithium‐ions storage, but also improve the charge transfer rate of the electrode. The testing electrochemical performances corroborated the standpoint: The Na−Mo−O/GO composites delivers specific capacities of 718 mAh g−1 after 100 cycles at 100 mA g−1, and 570 mAh g−1 after 500 cycles at a high rate of 500 mA g−1; for comparison, the bare Na−Mo−O nanorod shows a severe capacity decay, which deliver only 332 mAh g−1 after 100 cycles at 100 mA g−1. In view of the cost‐efficient and less time‐consuming in synthesis, and one‐step preparation without further treatment, these Na−Mo−O nanorods/GO composites present potential and prospective anodes for LIBs.

In virtue of high capacity and low manufacturing expense, transition metal carbonates (TMCs) have recently arisen enormous research interests as the anode materials for rechargeable lithium ion batteries (LIBs). However, the low electrical conductivity and unstable cycle performance impeded their further development. In this work, Co-B compounds are surface-engineered for the first time onto the mixed single-phase Mn 0.33 Co 0.67 CO 3 microspheres to accelerate the reaction kinetics and suppress the volume fluctuation of the electrodes during Li+ insertion/extraction. Specifically, Co-B nanoflakes not only function as the robust mechanical bridges between Mn 0.33 Co 0.67 CO 3 primary nanoparticles, but also provide extra pathways for electron/charge transport, both of which facilitate the improvement of electrochemical behaviors. Morever, the synergetic effect between Mn 0.33 Co 0.67 CO 3 and Co-B nanoflakes allow a high flux of Li+ across the interface to provide signifcantly boosted Li+ diffusivity. Impressively, the Mn 0.33 Co 0.67 CO 3 @Co-B electrode delivers a high reversible capacity of 806 mA h g−1 over 500 cycles at a high rate of 1.0 A g−1, demonstrating its superior cycling stability. Therefore, surface engineering of borides may be an effective and promising way to improve the electrochemical behaviors of conversion type anodes like TMCs. Image 1 [ABSTRACT FROM AUTHOR]
