ראה דגמי TF Hubברוכים הבאים ל- TensorFlow Hub Object Detection Colab! מחברת זו תעביר אותך דרך השלבים של הפעלת מודל זיהוי אובייקטים "מחוץ לקופסה" על תמונות.
עוד דגמים
זה האוסף מכיל TF2 מודלים זיהוי האובייקט כי הוכשרו על הנתונים COCO 2017. כאן תוכלו למצוא את כל הדגמים זיהוי האובייקט מתארחים כעת על tfhub.dev .
יבוא והגדרה
נתחיל בייבוא הבסיס.
# This Colab requires TF 2.5.pip install -U "tensorflow>=2.5"

כלי עזר
הפעל את התא הבא כדי ליצור כמה כלי עזר שידרשו מאוחר יותר:
- שיטת עוזר לטעינת תמונה
- מפה של שם הדגם לידית TF Hub
- רשימה של tuples עם נקודות מפתח אנושיות עבור מערך הנתונים של COCO 2017. זה נחוץ עבור דגמים עם נקודות מפתח.

כדי להמחיש את התמונות עם התיבות הנכונות שזוהו, נקודות המפתח והפילוח, נשתמש ב- TensorFlow Object Detection API. כדי להתקין אותו נשכפל את ה-repo.

בנו מודל זיהוי והעמסו משקולות של דגם מאומן מראש
כאן נבחר באיזה דגם Object Detection נשתמש. בחר את הארכיטקטורה והיא תיטען אוטומטית. אם אתה רוצה לשנות את המודל כדי לנסות ארכיטקטורות אחרות מאוחר יותר, פשוט שנה את התא הבא והפעל את הבאות.
טיפ: אם אתם רוצים לקרוא עוד פרטים על הדגם הנבחר, אתה יכול לעקוב אחר הקישור (ידית דגם) ולקרוא מסמכים נוספים על Hub TF. לאחר שתבחר דגם, נדפיס את הידית כדי להקל.

טוען תמונה
בואו ננסה את הדגם על תמונה פשוטה. כדי לעזור בכך, אנו מספקים רשימה של תמונות בדיקה.
הנה כמה דברים פשוטים שכדאי לנסות אם אתה סקרן:
- נסה להפעיל מסקנות על התמונות שלך, פשוט העלה אותן ל-colab וטען באותו אופן שזה נעשה בתא למטה.
- שנה חלק מתמונות הקלט ובדוק אם הזיהוי עדיין עובד. כמה דברים פשוטים שכדאי לנסות כאן כוללים היפוך התמונה אופקית, או המרה לגווני אפור (שים לב שאנחנו עדיין מצפים שלתמונת הקלט יהיו 3 ערוצים).
היזהר: כאשר באמצעות תמונות עם ערוץ אלפא, המודל מצפה 3 תמונות ערוצי ואת אלפא תיחשב -4.

עושה את ההסקה
כדי לעשות את ההסקה, אנחנו רק צריכים לקרוא לדגם הטעון TF Hub שלנו.
דברים שאתה יכול לנסות:
- הדפס
result['detection_boxes']ולנסות להתאים את מיקומי התיבה אל התיבות בתמונה. שימו לב שהקואורדינטות ניתנות בצורה מנורמלת (כלומר, במרווח [0, 1]). - בדוק מפתחות פלט אחרים הקיימים בתוצאה. ניתן לראות תיעוד מלא בדף תיעוד הדגמים (הפניית הדפדפן אל ידית הדגם שהודפסה קודם לכן)
# running inference
results = hub_model(image_np)
# different object detection models have additional results
# all of them are explained in the documentation
result = {key:value.numpy() for key,value in results.items()}

כאן נצטרך את ה-API לזיהוי אובייקטים של TensorFlow כדי להציג את הריבועים משלב ההסקה (ונקודות המפתח כאשר זמינות).
