Objective: This paper proposes a novel video compression by employing a technique which compensates the motion through using the blocks in varying sizes. Methods/Statistical Analysis: The video compression is achieved through the means of each block which vary in size using an accuracy algorithm which is selective in nature. This is a considerable improvisation upon the traditional approach of a wavelet transformation. The RDWT retains the information of the phase in the wavelet transform and provides the predicted enumeration for ME/MC related to transform domain. Findings: This effort focuses more on a reconciliation scheme of separation along with the selection norm which employs the motion content of the frame in a more effective manner with respect to shape and size of each block. Results: The investigational outcomes proved the effectiveness of proposed MH-VBSMC in the angle of using less number of separation blocks. Application/Improvements: This technique uses less computational steps.Keywords

The main intention of Fractal Image Compression is to reduce the size of image and maintain good level of their reconstructed image. A major issue in Fractal Image Compression is decrease in image quality, compression ratio and PSNR. To overcome these issues we employ Fractal transformation with entropy coding. There are two phases in the proposed approach. In the first phase color images are separated into three RGB planes using variable range block size. In second phase by applying the inverse transform and iterative functions the image is restored. It is observed that the results are improving in fractal compression for both gray images as well as color images. In this work high CR and PSNR is observed compared to fixed block range and other existing methods. The proposed work yields better CR of 20 and high PSNR.Keywords

Background/objectives: The availability of nutrients to plants is one of the main constraints under calcareous soil. This study aimed to investigate the influence of humic acid on nutrients availability and fruit yield of apple trees. at district Ziarat using red delicious apple variety of same age. Methods: Six rates of humic acid were tested in randomized complete block design (RCBD) with three replications. These rates were included as T1 = Control (0.0 g Humic acid), T2 = 50 g potassium humate tree-1, T3 = 75 g potassium humate tree-1, T4 = 100 g potassium humate tree-1, T5 =125 g potassium humate tree-1 and T6 = 150 g potassium humate tree-1. Findings: The results showed that the apple trees received 125 and 150 g potassium humate tree-1 recorded statistically at par but higher fruit set (71.68 and 74.66%) and fruit yield (262.15 and 264.46 kg tree-1) and higher fruit retention (91.63%) with minimum fruit drop (8.37%) at 150 g potassium humate tree-1. However, control treatment resulted in greater fruit drop (72.43%) and minimum fruit set (21.10%). Similarly, the application of 125 and 150 g potassium humate tree-1 manifested higher leaf macro and micro nutrients concentration. There was positive and significant correlation between apple fruit yield and leaf nutrient concentration which evidenced the beneficial and stimulatory effect of humic acid on nutrient availability and yield. Applications/improvements: From this study it is suggested that different sources of humic acid need to be tested on apple so that the best source of humic acid can be found for quality fruit production of apple.
