Research on Low Frame Rate Video Compression Algorithm in the Context of New Media

“…Its unique artistic form and expression bring people a dreamlike feeling. At present, animation has gradually penetrated into every link of human life with its fascinating magic [9]. New media is a new media form under network technology, computer technology, and multimedia technology, such as digital magazine, mobile TV, virtual university, online blog, virtual studio, and so on.…”

Multiplexed structured illumination super-resolution imaging with lifetime-engineered upconversion nanoparticles

“…In search of the potential probe candidates, most of the nanoparticles such as quantum dots [11][12][13], carbon dots [14,15], and organic dyes [16][17][18] show short lifetimes in nanoseconds, limiting the channels for lifetime multiplexing. In contrast, lanthanide-doped upconversion nanoparticles (UCNPs) have attracted significant attention due to the stable anti-stocks shift emission [19][20][21][22] and the tunable lifetime from microsecond to millisecond [6,[23][24][25]. Moreover, the lifetime can be tuned by changing the doping concentration of rare-earth ions, changing various kinds of emitter ions, or using different exciting lasers.…”

Multipath optical thermometry realized in CaSc2O4: Yb3+/Er3+ with high sensitivity and superior resolution

“…Upconversion (UC) luminescence is referred to radiate ultraviolet or visible light through absorbing two or more near‐infrared photons with low energy 1‐4 . Benefiting from such a unique optical property, UC materials have attracted much attention for the application of drug delivery, biological imaging, photodynamic therapy, photothermal therapy, three‐dimensional display, etc 5‐9 . In the past few years, UC materials have also been found to own outstanding temperature sensing properties which can afford a contactless thermometry in many special industries, such as coal mining, metal smelting, petrochemicals, biomedicine, and so on 10,11 .…”

“…[1][2][3][4] Benefiting from such a unique optical property, UC materials have attracted much attention for the application of drug delivery, biological imaging, photodynamic therapy, photothermal therapy, three-dimensional display, etc. [5][6][7][8][9] In the past few years, UC materials have also been found to own outstanding temperature sensing properties which can afford a contactless thermometry in many special industries, such as coal mining, metal smelting, petrochemicals, biomedicine, and so on. 10,11 In particular, the fluorescence intensity ratio (FIR) between two thermally coupled energy levels of trivalent rare earth ions is considered to be a promising technology to provide fast and accurate optical thermometry, due to its rapid response capability, high spatial resolution, strong anti-jamming ability, etc.…”
