In the present study, we found that blue light stress negatively affected the development periods, body weight, survival and reproduction of Spodoptera frugiperda, and it showed a dose-dependent reaction, as longer irradiation caused severer effects.

The IWT (Integer Wavelet Transform) can achieve genuine lossless image compression and allow both lossy and lossless compression using a single bit-stream. However, using the IWT instead of the DWT (Discrete Wavelet Transform) will degrade the perfor

Multiple Region of Interest (ROI) coding is important in applications where some parts of the image are of higher importance than others and need to be encoded at higher quality than the background. The new image coding standard JPEG2000 recommended

Region of Interest (ROI) coding belong to the efficient region-based image compression method and is an important feature of JPEG2000 standard. In this paper, a new ROI coding method is proposed. In the method, we utilize the improved SPECK algorithm

Integer wavelet transform (IWT) and IWT-based image coding offer many advantages over traditional wavelet. But coefficient magnitudes of the IWT-image have smaller dynamic change value and worse energy compaction than the first generation wavelet. Th

Image compression based on region of interest (ROI) means to code the important regions in an image with high quality and to code other regions (Background-BG) with relatively low quality. Based on this idea, a flexible ROI image coding method called
