Image Quality Assessment using Image Details in Frequency Domain
This research proposes a RR (Reduced Reference) DIQAM (Detailed Image Quality Assessment Meter)
for DCT (Discrete Cosine Transform) based compressed images. DCT technique divides image in sub
blocks to achieve image compression.Therefore, it degrades the IQ (Image Quality) by introducing the
distortions called blockiness and blurriness in the compressed image.In the telecommunication systems
scenario, the systems available bandwidth is limited. The proposed IQ assessment technique requires
fewer image details parameters called RR parameters at the receiver, rather than the complete reference
image. This paper suggests a method for receiving end to estimate the objective quality of the received
image in frequency domain.The proposed IQ meter starts by taking the image through edge detection
method, then converting it into frequency domain by Fourier transform and estimating the image details.
The image details calculations include the vertical and horizontal ac harmonics as well as all other ac
coefficients present in the image. It has been shown in the presented work that using dc coefficients with
the other ac coefficients further improves the quality assessment.The calculated strength of coded image
details at receiver is compared with the received RR parameter for the estimation of distortions, blockiness
and blurriness. The accuracy of the designed RR DIQAM algorithm is proved by correlating the estimated
objective values of the distortions with the LIVE image database2 subjective DMOS values of blockiness
and blurriness. The results obtained by the proposed technique are well matched with the LIVE database
values and provide 94-96% correlation
The Golden Rule:Interfaith Peacemaking and the Charter for Compassion
The Charter for Compassion has been signed by over two million people from around the world and partnered with hundreds of interfaith organizations and cities seeking to put into practice the Golden Rule, common to the main faith traditions, of doing unto others as you would be done by. This article sets the Charter within the context of a post secular international society and faith-based diplomacy, in which religious interreligious initiatives emerge as serious, rather than peripheral, actors in developing sustainable peace making through bottom-up approaches. The article critically engages with the Charter's claim that ‘any interpretation of scripture that breeds violence, hatred or disdain is illegitimate’ while accepting that peaceful interpretations of scriptures are helpful to peace processes where religious actors are involved. The article explores the claims of the Charter for Compassion International as they seek to make peace through compassion, before concluding that the Charter for Compassion is a long-term project aimed at changing hearts and minds but has had limited substantive impact to date
