(Saib cov qauv kab lus saum toj no)

Mob ntshav qab zib retinopathy yog mob ntshav qab zib ntsig txog qhov muag tshwm sim los ntawm cov ntshav qab zib ntau ntau. Cov ntshav qab zib ntau ntau ua rau cov hlab ntshav hauv cov retinas ua rau o, uas ua rau cov hlab ntsha loj tuaj thiab txawm tias lub nkoj xau, uas ua rau pom qhov tsaus ntuj hauv cov duab retinal. Nrog txoj cai no, peb lub hom phiaj siv cov tsos mob ntawm cov hlab ntshav tawm los ua qhov taw qhia ntawm keeb kwm yav dhau los ntawm kev mob ntshav qab zib retinopathy, txawm hais tias yuav tsum tau siv cov txheej txheem kuaj mob ntxiv hauv ntiaj teb tiag. Lub hom phiaj ntawm txoj cai no yog siv lub tshuab ua duab zoo thiab kuaj pom cov duab retinal los txheeb xyuas cov tsos mob ntawm tus mob ntshav qab zib retinopathy pom los ntawm qhov tsaus ntuj hauv cov duab retinal.

10 cov duab qub qub thiab 10 qhov kuaj pom cov duab retinal tau ua tiav los ntawm tus lej uas xub nyeem thiab lim cov duab thiab tom qab ntawd suav qhov tsaus ntuj los txiav txim siab yog tias muaj cov tsos mob ntshav qab zib retinopathy, tam sim no, raws li qhov pib muab. Cov txiaj ntsig tau luam tawm mus rau lub qhov rai hais kom ua rau cov neeg txhais lus.

Kauj Ruam 25: Tshem Tawm Cov Roj Ntshav Hauv Duab

Tshem tawm cov hlab ntsha tseem muaj nyob hauv daim duab siv bwpropfilt muaj nuj nqi nrog [0, 0.9].

[0.9, 1] raug tshem tawm vim tias qhov tseem ceeb ze rau 1 qhia txog kab. Muab rau "RemoveVessels".

Kauj Ruam 26: Daim Duab Zaub

Tso tawm txhua cov duab lim hauv ib qho subplot. Imshow. nrog 'ciam teb' thiab 'nruj' cov tswv yim, qhia tawm txhua daim duab hauv cov qauv txheej txheem. Ntxiv lub npe rau txhua daim duab kom paub qhov txawv uas lim tau siv.

Kauj Ruam 27: Tshem Tawm Lub Nkoj thiab Suav Blobs Cov Ntshav

1. Siv "RemoveVessels" thiab siv 'Centroid' qhov tshwj xeeb hauv cheeb tsam cov khoom siv los txheeb xyuas cov centroids ntawm cov khoom hauv daim duab. Cov khoom no yuav tsum sib haum nrog cov ntshav txhaws tam sim no hauv daim duab.

2. Suav cov naj npawb ntawm cov ntshav uas tau txheeb xyuas los ntawm kev siv qhov ntev ntawm lub hauv paus nruab nrab.

Kauj Ruam 28: Txheeb Xyuas Cov Duab Retinal Raws Li Tus Zauv Cov Ntshav Ntshav Ntshav

Siv yog cov lus los txheeb xyuas cov duab raws tus naj npawb ntawm cov ntshav txhaws tau txheeb xyuas.

Yog tias tus lej ntawm cov cim hauv nruab nrab tau tsawg dua lossis sib npaug rau 5, daim duab tau txheeb pom tias zoo li qub.

Yog tias tus lej ntawm cov centroids ntau dua 5, daim duab tau kuaj pom tias muaj ntshav qab zib retinopathy.

Qhov txiaj ntsig tau luam tawm rau ntawm lub qhov rai hais kom ua siv fprintf.

Kauj Ruam 29: Yog Muaj Ntau Tshaj 5 Blobs …

Rov hais dua cov lus qhia saum toj no rau cov duab kuaj mob raws li lwm nqe lus. Qhov no yuav ua haujlwm yog tias tus lej blobs ntau dua 5.

Xaus qhov lus hais.

Kauj Ruam 30: Rov Ua Dua Cov Txheej Txheem rau Cov Duab Ib Leeg Nrog Duab Zauv Tus Nqi Raws Li 2 thiab 3

Rov ua cov txheej txheem rau qhov seem ntawm qhov qub yog cov lus hais thaum tus lej (tus lej ntawm tus lej hauv daim duab) yog sib npaug rau 2 thiab 3. Qhov no ua tiav rau lub voj rau cov duab ib txwm muaj.

Xaus qhov rau lub voj.

Kauj Ruam 31: Rov Ua Dua Cov Txheej Txheem rau Cov Duab Diagnosed

Rov ua dua tag nrho cov txheej txheem siv cov duab kuaj pom los ntawm matrix "numbers_to_extract_diagnosed".

Nco ntsoov hla txhua daim duab (i) thiab hloov nws mus rau daim duab (i+10) yog li cov duab kuaj pom yuav tshwm li cov duab 11 txog 20.

Kauj Ruam 32: Txheeb cais

1. 'Qhov tseeb_Diagnosis_Matrix' yog siv los sib piv cov txiaj ntsig mus rau qhov kev kuaj mob pom nyob hauv cov ntaub ntawv txt. Thawj 10 zeros qhia tias thawj 10 cov duab yuav tsum yog ib txwm muaj. 10 qhov kawg qhia tias 10 daim duab kawg yuav tsum tau muab cais ua ntshav qab zib retinopathy.

2. Ob npaug sib npaug kos npe siv los tsim 'number_correct' tsim cov laj thawj los ntawm kev sib piv tus nqi ntawm cov ntsiab lus sib xws ntawm 'Qhov tseeb_Diagnosis_Matrix' rau 'Diagnosis_Matrix' tsim los ntawm lub voj.

Rau txhua lub ntsiab lus uas phim qhov kev kuaj mob a 1 yuav raug ntxiv, txhais tau tias cov cai raug txheeb xyuas cov duab ntawd. Yog tias nws tsis raug nws yuav ntxiv 0 rau hauv matrix.

Tom qab ntawd, suav tag nrho qhov ntawd ntxiv rau txhua qhov. Hauv lwm lo lus, nws pom cov txiaj ntsig ntawm cov duab kuaj pom raug.

3. 'Final_percentage_correct' yog xam feem pua ntawm qhov tseeb qhov chaws kuaj mob ntshav qab zib retinopathy. Tus naj npawb ntawm cov duab kuaj pom raug muab faib los ntawm 20 (tag nrho cov duab) thiab muab sib npaug los 100 kom pom qhov feem pua ntawm kev kuaj mob ua tiav.

Kauj Ruam 33: Nrhiav Kev Ntseeg Siab

1. Xyuas kom koj muaj ModWald.m rub tawm los hu nws ua haujlwm. Tsis muaj lub luag haujlwm, koj yuav tsum tau suav qhov kev ntseeg siab ib ntus siv qhov hloov pauv Wald txoj kev koj tus kheej.

2. ModWald muaj nuj nqi muaj 2 lub tswv yim qhov twg thawj yog tus lej ntawm cov duab raug txheeb xyuas, thiab qhov thib ob yog tag nrho cov duab.

3. ModWald muaj nuj nqi yuav tso tawm qhov qis thiab sab saud ntawm qhov kev ntseeg siab ntawm qhov sib piv rau qhov raug ntawm cov ntaub ntawv piv txwv. Hauv lwm lo lus, nws yuav koj muab ntu luv ntawm qhov feem pua qhov tseeb qhov tseeb ntawm qhov raug ntawm cov cai yuav dag.

4. Siv fprintf hauv qab no los tso tawm cov txheeb cais thiab kev cog qoob loo mus rau qhov hais kom ua qhov rai.

> fprintf ('%. 0f feem pua ntawm cov duab retinal raug kuaj pom tseeb raws li kev kuaj mob. / n / n', Final_percentage_correct)

> fprintf ('Qhov feem pua tseeb uas peb tus lej yuav raug kuaj mob ntshav qab zib retinopathy yuav / n poob mus rau qhov ntau ntawm [%.3f, %.3f], raws li 20 cov duab piv txwv / n', qis dua, sab saud)
