| 1 | Effect of Direct Statistical Contrast Enhancement Technique on Document Image Binarization显示文摘Background:Contrast enhancement plays an important role in the image processing field.Contrast correction has performed an adjustment on the darkness or brightness of the input image and increases the quality of the image.Objective:This paper proposed a novel method based on statistical data from the local mean and local standard deviation.Method:The proposed method modifies the mean and standard deviation of a neighbourhood at each pixel and divides it into three categories:background,foreground,and problematic(contrast&luminosity)region.Experimental results from both visual and objective aspects show that the proposed method can normalize the contrast variation problem effectively compared to Histogram Equalization(HE),Difference of Gaussian(DoG),and Butterworth Homomorphic Filtering(BHF).Seven(7)types of binarization methods were tested on the corrected image and produced a positive and impressive result.Result:Finally,a comparison in terms of Signal Noise Ratio(SNR),Misclassification Error(ME),F-measure,Peak Signal Noise Ratio(PSNR),Misclassification Penalty Metric(MPM),and Accuracy was calculated.Each binarization method shows an incremented result after applying it onto the corrected image compared to the original image.The SNR result of our proposed image is 9.350 higher than the three(3)other methods.The average increment after five(5)types of evaluation are:(Otsu=41.64%,Local Adaptive=7.05%,Niblack=30.28%,Bernsen=25%,Bradley=3.54%,Nick=1.59%,Gradient-Based=14.6%).Conclusion:The results presented in this paper effectively solve the contrast problem and finally produce better quality images. | Wan Azani Mustafa Haniza Yazid Ahmed Alkhayyat Mohd Aminudin Jamlos Hasliza A.Rahim | 2022 | Computers, Materials & Continua2022，，2： | 1 |

| 10 | Physico-Chemical Study of Silica Rocks from the East Coast Malaysia Region for Crystal Glass Application显示文摘The main objective of the current work is to recover SiO2 various acid concentrations,scrubbing time,and attrition impeller speed for crystal glass application.Silica rocks were treated using a physico-chemical method involving physical separation method using citric and sulphuric acids as the reagents.Low acid concentration range of 1%-2%and variable scrubbing time of 10,20,and 30 min were investigated.The microstructure,phase,and particle size of the silica rocks were determined after scrubbing process.Citric acid was found effective in improving the purity of SiO2 to 99.8%at 0.75%concentration,via a 20 min scrubbing process operated at 1,250 rpm(rotations per minute).The phase structure and morphology of the recovered SiO2 were confirmed as trigonal crystal structure with small and irregular shape.To date,studies on the processing of silica rock using organic acid are yet very limited. | Syarifah Aminah Ismail Muhammad Kamal Kamarudin Mohamad Haniza Mahmud Mohd Idham | 2020 | Journal of Geological Resource and Engineering2020，8，4： | 0 |

| 12 | Contrast Correction Using Hybrid Statistical Enhancement on Weld Defect Images显示文摘Luminosity and contrast variation problems are among the most challenging tasks in the image processing field,significantly improving image quality.Enhancement is implemented by adjusting the dark or bright intensity to improve the quality of the images and increase the segmentation performance.Recently,numerous methods had been proposed to normalise the luminosity and contrast variation.A new approach based on a direct technique using statistical data known as Hybrid Statistical Enhancement(HSE)is presented in this study.TheHSE method uses themean and standard deviation of a local and global neighbourhood and classified the pixel into three groups;the foreground,border,and problematic region(contrast&luminosity).The datasets,namely weld defect images,were utilised to demonstrate the effectiveness of the HSE method.The results from the visual and objective aspects showed that the HSE method could normalise the luminosity and enhance the contrast variation problem effectively.The proposed method was compared to the two(2)populor enhancement methods which is Homomorphic Filter(HF)and Difference of Gaussian(DoG).To prove the HSE effectiveness,a few image quality assessments were presented,and the results were discussed.The HSE method achieved a better result compared to the other methods,which are Signal Noise Ratio(8.920),Standard Deviation(18.588)and Absolute Mean Brightness Error(9.356).In conclusion,implementing the HSE method has produced an effective and efficient result for background correction and quality images improvement. | Wan Azani Mustafa Haniza Yazid Ahmed Alkhayyat Mohd Aminudin Jamlos Hasliza ARahim Midhat Nabil Salimi | 2022 | Computers, Materials & Continua2022，，6： | 0 |
| 13 | Quality of life of parents and siblings of children with cochlear implants显示文摘Objectives: This study examined the quality of life(QoL) of the parents and siblings of hearing-impaired children with cochlear implants(CIs).Design: This is a cross-sectional, questionnaire-based study. The questionnaire consists of three sub-domains-interaction, emotional well-being and support for the hearing-impaired child and the overall QoL – and two open-ended questions for participants to provide comments and suggestions to enhance their family's QoL. A total of 63 questionnaires were e-mailed or mailed to families who met the inclusion criteria.Setting: The study was conducted under the Center for Rehabilitation & Special Needs, Faculty of Health Sciences, Universiti Kebangsaan Malaysia, Kuala Lumpur.Participants: A total of 79 parents and 23 siblings from 44 families of children with CI participated in this study.Main outcome measures: The mean score for each of the sub-domain and the overall QoL for both subject groups were computed. The answers for the open-ended questions were listed and organized into themes.Results: There were significant correlations between the overall QoL score and each of the test domains for the parents' group(p < 0.01). For the siblings' group, only the interaction and support domains were significant.Interaction was the main sub-domain affecting the parents' QoL but for siblings, this could not be determined. A total of 60% of the pooled comments were classified as ‘concerns'. As for the suggestions, 38.7% requested some form of support, mainly financial(41.7%).Conclusions: Families with hearing impaired children with CI have numerous concerns that need to be addressed, even though, on average, they were satisfied with their overall QoL. | Cila Umat Nor Haniza Abdul Wahat Sakinah Che Ross Bee See Goh | 2019 | Journal of Otology2019，14，1： | 0 |
