To run you must install .Net Framework: v2.0
When you have developed a .NET application and then you want to run the executable file, you may get the following error:
"To run you must install .Net Framework: v2.0.50727 ..."
Simply, just download the Microsoft .NET Framework and install on your PC. Some cases, restart the PC is required.
Cheers..

My paper in the Springer LNCS
My paper entitled "Quasi-Gaussian DCT Filter for Speckle Reduction of Ultrasound Images" has been accepted for publishing in the Springer-Verlag Lecture Notes of Computer Science series.
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.

Tetanggaku positif H1N1 !!
Swine influenza (flu babi) telah menghebohkan dunia. Seminggu yang lalu, WHO merilis bahwa sedikitnya 700 pengidap penyakit ini telah meninggal dunia. Kemarin saya berfikir begini: Beberapa waktu yang lalu, kita baca berita bahwa influenza H1N1 telah berjangkit dan menelan korban di Meksiko, Amerika, Eropa, Korea, Jepang. Terus mendekat...Thailand, Indonesia dan Malaysia. Setelah beberapa sekolah di Kuala Lumpur ditutup untuk menekan penyebaran virus, menyusul kemudian adalah UITM, UPNM dan UKM-KL. Wabah ini terus saja mendekat dan mendekat ke rumah kita. Ya, bukan sekedar berita di media tapi sudah ada tetangga kita yg terkena. Mulai hari ini, UPM resmi dikarantina karena 4 pelajarnya positif terjangkit selesema 'hebat' ini. UPM di Serdang, UKM di Bangi, tanpa batas lagi!Pagi tadi setelah anak-anak semua mandi, saya briefing mereka ttg kondisi terkini virus ini. Empat hal yang perlu diperhatikan:
1. OBSERVASI DIRI. Kenali dan pantau kondisi masing-masing: suhu badan, demam, sakit tekak/tenggorokan, flu, pegal-pegal. Kalau ada salah satu symptom tadi, segera konsultasi dokter.
2. WASPADA dengan LINGKUNGAN. Hindarkan pergi ke tempat-tempat umum, kecuali keharusan. Selalu gunakan masker penutup hidung/mulut bila harus berinteraksi dg ramai orang. Kita tidak tahu siapa dan dimana, betul kan?
3. TINGKATKAN STAMINA. Seperti flu burung dan SARS, virus ini sangat melemahkan daya tahan tubuh. Bila stamina rendah, sangat rentan tertular flu ini. Oleh karena itu, harus makan makanan bergizi, buah, sayuran, dan suplemen penambah daya tahan tubuh.
4. DOA dan TAWAKAL, smg Allah berikan kesehatan dan terhindar dari bencana wabah ini.
Subhanallah, Engkau tunjukkan lagi kekuasaan-Mu. Manusia memang tidak berdaya, pun hanya dengan influenza. Semoga kami sadar, sungguh sangat tidak patut kami bersombong.
