Abstract. In recent time, ultrasound imaging is a popular modality for various medical applications. The presence of speckle noise affects difficulties on features extraction and quantitative measurement of ultrasound images. This paper proposes a new method to suppress the speckle noise while attempting to preserve the image content using combination of Gaussian filter and discrete cosine transform (DCT) approach. The proposed method, called quasi-Gaussian
DCT (QGDCT) filter, is a quasi Gaussian filter in which its coefficients are derived from a selected 2-dimensional cosine basis function. The Gaussian approach is used to suppress speckle noise whereas the selected DCT approach is intended to preserve the image content. The filter will be implemented on the synthetic speckle images and the clinical echocardiograph ultrasound images.
To evaluate the effectiveness of the filter, several quantitative measurements such as mean square error, peak signal to noise ration, speckle suppression index and speckle statistical analysis, are computed and analyzed. In comparison with established filters, results obtained confirmed the effectiveness of QGDCT filter in suppressing speckle noise and preserving the image content.
Keywords: Gaussian, DCT, speckle, ultrasound image, echocardiography

Malaysia gudang petir. HOUWGH...
Kejadian petir atau halilintar bertubi-tubi seperti ini memang biasa terjadi di Malaysia. Ini sejauh pengamatan saya selama tinggal lima tahun di sini. Kalau dibandingkan dengan di Solo atau Yogyakarta, rumah saya di Indonesia, petir di Malaysia lebih mengerikan baik dari segi kuantitas maupun kualitas. Jumlahnya lebih banyak dan lebih besar suara maupun kilatan cahayanya. Seperti di atas kepala.
Petir: Fenomena apa?
Petir adalah kejadian alam biasa. Bukan dewa marah, penunggu gunung batuk atau cerita-cerita khayal jaman dulu yang kadang digunakan untuk menakut-nakuti anak-anak. Petir terjadi karena perbedaan potensial antara awan dan bumi atau antar awan. Muatan pada awan terjadi karena sebagian awan bergerak dan berinteraksi secara teratur. Bila perbedaan potensial sudah cukup besar dan media memungkinkan, maka akan terjadi aliran elektron dari muatan negatif ke positif. Dan terjadilah petir.
Ingin mencoba membuat petir?
Mudah. Cukup sediakan aki atau baterai yang masih bagus. Pasang kabel pada salah satu polaritas. Kemudian sentuhkan ujung kabel yang lain pada polaritas satunya. Ingat, cukup sentuhkan, jangan ditempelkan atau disambung karena akan membakar kabel atau merusakkan baterai/aki. Nah, apa yang terjadi? CLARKK...akan timbul bunga api. Anda telah membuat petir kecil-kecilan. Memang kecil, baterai cuma 1.5 volt, sedangkan petir bisa mencapai 10 juta volt. Houwgh...
Kenapa petir terjadi sebelum/semasa hujan?
Ya, seperti saya tulis di atas, elektron perlu media untuk bisa mengalir. Nah, pada saat hujan, kandungan air di udara adalah tinggi sehingga air menjadi medium untuk memudahkan mengalirnya elektron sehingga terjadi petir.
Bagaimana dengan suara guruh?
Petir berupa kilatan, biasanya diikuti dengan suara guruh, atau gludhuk dalam Bahasa Jawa. Suara guruh terjadi karena terjadinya pemanasan yang luar biasa ketika udara dilewati petir. Bayangkan, suhu atmosfer bisa mencapai 20.000 derajat C (sekitar 3 kali suhu permukaan matahari). Wuihh..masyaAllah. Kejadian ini menghasilkan kompresi udara dan akhirnya meledak sehingga menghasilkan suara gemuruh yang tidak kalah dahsyat.
Kenapa guruh terdengar setelah kilat?
Sebenarnya peristiwa kilat dan guruh terjadi pada masa yang bersamaan. Suara guruh terdengar beberapa saat setelah terlihat kilat karena cahaya merambat lebih cepat (186.000 miles per detik) dibandingkan suara (sekitar 700 mil per jam).
NASA, badan antariksa Amerika Serikat, memetakan distribusi populasi petir seluruh dunia seperti gambar di bawah ini.
Sebentar, petir mau datang lagi. Saya harus mengamankan semua barang elektronik dulu. Ntar dilanjut...

Tips: Menyelamatkan HP yang 'berenang' tercelup air
1. Setelah tercebur air, jangan coba-coba ON-kan HP karena malah bisa berakibat rangkaian menjadi konslet.
2. Segera lepaskan bateray, simcard dan cover HP. Tujuannya adalah utk menjangkau sedalam mungkin bagian HP.
3. Keringkan HP selama 2-3 hari. Cara mengeringkan bisa dengan menjemur atau menggunakan hair-dryer. HP saya ketika itu saya masukkan dalam bagasi dan mobil dipanggang di bawah terik matahari.
4. Setelah pengeringan, coba ON-kan. Dan.... thing thung... HP Anda kembali bisa digunakan.
Bila tips ini tidak mempan mengobati HP Anda, silahkan hubungi 'dokter'.... Wassalam.

How are universities ranked?
Sebagai alumni, salut deh buat UGM. Tapi sebenarnya, menurut saya yg hebat adalah 'TIM WEB UGM', bukan UGM itu sendiri. Loh kok ngono? Iyo, karena Webomatrics adalah 'world universities' ranking on the web'. Artinya Tim Web UGM telah berhasil 'memamerkan UGM' dalam dunia maya, ya to?
"Lha nek dudu ranking sing neng web, UGM ki nomer piro le?"
"Wah susah njawabnya mbak.. :-("
Sebenarnya banyak sekali ranking universitas yg dibuat oleh berbagai institusi, baik lokal maupun internasional, bisa di-refer di sini. Universitas2 di Malaysia banyak me-refer dan berusaha menaikkan ranking universitas versi THES, the Times Higher Education Supplement. Indonesia (baca: DIKTI) dengan Webomatrics-nya. Tiap-tiap versi ranking punya pendekatan masing-masing, yg meliputi criteria, indikator dan bagaimana measurement process nya.
Sebagai contoh, coba kita copy-paste criteria yg dipake oleh tiga versi peranking yg cukup dikenal: THES, Shanghai (ARWU) dan Webomatrics. Yg terakhir dipilih karena ini yg dipakai DIKTI.
1. THES-QS
Indicator | Explanation | Weighting |
---|---|---|
Academic Peer Review | Composite score drawn from peer review survey (which is divided into five subject areas). 6,354 responses in 2008. | 40% |
Employer Review | Score based on responses to employer survey. 2,339 responses in 2008. | 10% |
Faculty Student Ratio | Score based on student faculty ratio | 20% |
Citations per Faculty | Score based on research performance factored against the size of the research body | 20% |
International Faculty | Score based on proportion of international faculty | 5% |
International Students | Score based on proportion of international students | 5% |
Detail-nya, silahkan baca di sini.
2. Shanghai (Academic Ranking of World Universities). Baca lengkap di sini.
Criteria | Indicator | Code | Weight |
Quality of Education | Alumni of an institution winning Nobel Prizes and Fields Medals | Alumni | 10% |
Quality of Faculty | Staff of an institution winning Nobel Prizes and Fields Medals | Award | 20% |
Highly cited researchers in 21 broad subject categories | HiCi | 20% | |
Research Output | Articles published in Nature and Science* | N&S | 20% |
Articles indexed in Science Citation Index-expanded, and Social Science Citation Index | PUB | 20% | |
Per Capita Performance | Per capita academic performance of an institution | PCP | 10% |
Total | 0 | 0 | 100% |
3. Webomatrics
Size (S). Number of pages recovered from four engines: Google, Yahoo, Live Search and Exalead. For each engine, results are log-normalised to 1 for the highest value. Then for each domain, maximum and minimum results are excluded and every institution is assigned a rank according to the combined sum. --> 50%
Visibility (V). The total number of unique external links received (inlinks) by a site can be only confidently obtained from Yahoo Search, Live Search and Exalead. For each engine, results are log-normalised to 1 for the highest value and then combined to generate the rank. --> 20%
Rich Files (R). After evaluation of their relevance to academic and publication activities and considering the volume of the different file formats, the following were selected: Adobe Acrobat (.pdf), Adobe PostScript (.ps), Microsoft Word (.doc) and Microsoft Powerpoint (.ppt). These data were extracted using Google and merging the results for each filetype after log-normalising in the same way as described before. --> 15%
Scholar (Sc). Google Scholar provides the number of papers and citations for each academic domain. These results from the Scholar database represent papers, reports and other academic items. --> 15%
Nah, sekarang kita bisa lihat, bagaimana mereka menentukan ranking tersebut. Sungguh sangat beda. Perbedaan criteria dan weighting sangat berpengaruh pada hasil ranking.
"Lha terus versi mana yg kita sebaiknya ikuti le?"
"Wah itu tergantung demand mas..."
Maksudnya, masa' ya UGM mo ngikuti ranking versi THES ato Shanghai, ga bakalan ketemu kalau sampeyan nyari. Buktiin di sini dan situ. Saya memahami bahwa dalam rangka 'image building', memang betul langkah DIKTI utk menggunakan versi Webomatrics, karena di versi inilah nama unversitas2 indonesia (paling tidak) muncul. Dan saya faham juga kenapa UKM selalu nge-push postgraduate students utk publish di journal impak tinggi.
Wis berhenti mbaca blog, mari kita lanjutin nulis paper utk submit ke high-impact-journal....!

Abstract:
Detection of cardiac movement is very important subject on cardiac image analysis. Cardiologist needs an accurate motion estimation to diagnose the abnormality of cardiac. In this paper, we present the utilization of optical flow technique to estimate the myocardial motion. Then the computed motion vectors are used to provide the cardiac profile, such as its displacement and direction. The proposed implementation provides real-time movement profiles of cardiac with a precision up to 0.11 pixel / 22.50° for their displacements.
Keywords: optical flow, myocardial movement, cardiac profile, echocardiography
