P lants have been of the utmost importance since antiquity for a variety of reasons. It is common knowledge that plants are a significant source of natural compounds that can be used to develop cutting-edge drugs that can protect humans against a range of harmful infections (Suntar et al., 2018;Ibrahim et al., 2020). Drinking fruit juice aids in the preservation of good health and the prevention of numerous diseases. Humans frequently consume citrus fruit juice because of its distinctive flavor and nutritional benefits. Juice's favorable health effects have been attributed in part to its abundance of vitamin C (ascorbic acid) (Ibrahim & Muhammad, 2016;Klimek-Szczykutowicz et al., 2020). Citrus fruits contain a wide range of bioactive substances, such as phenolics, flavonoids, vitamins, and essential oils. These bioactive substances have been used as anti-inflammatory, anticancer, anti-oxidative, and antibacterial effects (Ibrahim et al., 2015; Al-Ghareebawi et al., 2021). In addition, lemon juice has a high ascorbic acid and citric concentration, which gives its acidic behavior (Ekawati & Darmanto, 2019;Singh et al., 2020).Plants can produce nitrogen compounds (amines, alkaloids), terpenoids (as well as carotenoids), vitamins, and endogenous metabolites (Henderson, et.al. 2018) in addition to aromatic molecules including quinones, flavonoids, phenolic acids, coumarins, stilbenes, lignans, and

“…The embedding process is carried out in DWT by modifying the cover-image's wavelet coefficients to attain a secure transmission. The component frequency band is split into four smaller bands called sub-bands namely low low 'LL', low high 'LH', high low 'HL', and high high 'HH' [30,31]. The major advantage of DWT is that it provides high robustness due to transforming the actual image into its wavelet coefficient [32].…”

<p>Information is a vitalthing that needs to be secured and well protected during transmission between two or more parties over the internet. This can be achieved by steganography technology. Steganography is the concealing science in which the information is concealed inside other information in a way that the concealed information cannot be detectable by the human eye. Many ways are available to hide data inside a cover media for example text, image, and audio steganography, but image steganography is the most utilized technique among the others. Secure image steganography has a high-security level than traditional technique by combining steganography with cryptography due to encrypting secret information by cryptography algorithm before embedding it into the cover media by steganography algorithm. In this paper,a systematic review has been presented about secure image steganography and its renowned types. Many researchers proposed secure image steganography by using various cryptography and steganography algorithms which have been reviewed. The least significant bit ‘LSB’ was the renowned steganography algorithm which has been used by researchers due to its simplicity, while various cryptography algorithms like advanced encryption standard (AES) and blowfishhave been used to propose secure image steganography in the reviewed papers. The comparison among the reviewed papers indicated that the LSB with hash-RSA gave a greater peak signal-noise ratio ‘PSNR’ value than the others which was 74.0189 dB.</p>

Computed tomography (CT) image-based medical recognition is extensively used for COVID recognition as it improves recognition and scanning rate. A method for intelligent compression and recognition system-based vision computing for CT COVID (ICRS-VC-COVID) was developed. The proposed system first preprocesses lung CT COVID images. Segmentation is then used to split the image into two regions: nonregion of interest (NROI) with fractal lossy compression and region of interest with context tree weighting lossless. Subsequently, a fast discrete curvelet transform (FDCT) is applied. Finally, vector quantization is implemented through the encoder, channel, and decoder. Two experiments were conducted to test the proposed ICRS-VC-COVID. The first evaluated the segmentation compression, FDCT, wavelet transform, and discrete curvelet transform (DCT). The second evaluated the FDCT, wavelet transform, and DCT with segmentation. It demonstrates a significant improvement in performance parameters, such as mean square error, peak signal-to-noise ratio, and compression ratio. At similar computational complexity, the proposed ICRS-VC-COVID is superior to some existing techniques. Moreover, at the same bit rate, it significantly improves the quality of the image. Thus, the proposed method can enable lung CT COVID images to be applied for disease recognition with low computational power and space.
