EasyOCR Detection of "Free" Boxes Doesn't Seem to Work

I have a program using EasyOCR that works great, but when I try to change it to use EasyOCR's detection of text with rotation/skewness etc., as opposed to just orthogonal boxes, (or as it's called in the documentation, the 'free_list', which is returned by easyocr.detect()), it does not seem to work. Specifically, here is the code and the output:

The code:

language = "en"
reader = easyocr.Reader([language], recognizer=False)
print(reader.detect(IMAGE_PATH))

The print() output: ([[[1739, 1922, 199, 266], [1965, 2774, 193, 262], [3047, 3168, 130, 241], [1459, 1616, 371, 435], [1649, 1796, 370, 434], [1822, 2161, 364, 433], [2184, 2676, 363, 430], [2718, 3001, 363, 427], [1455, 1546, 465, 517], [1593, 1792, 456, 518], [1813, 1918, 454, 515], [1977, 2156, 450, 516], [2201, 2313, 445, 521], [2345, 2997, 444, 518], [1446, 1670, 541, 603], [1777, 1921, 533, 598], [1957, 2073, 536, 598], [2121, 2590, 527, 601], [2628, 2769, 533, 595], [2803, 2978, 531, 595], [1439, 1650, 624, 685], [1690, 1747, 620, 677], [1787, 2037, 621, 683], [2070, 2233, 601, 686], [2277, 2395, 616, 680], [2447, 3041, 613, 680], [1478, 1579, 715, 772], [1622, 2047, 704, 773], [2190, 2332, 705, 762], [2368, 2608, 693, 765], [2635, 2777, 699, 760], [2806, 3040, 699, 763], [1445, 1758, 786, 859], [1798, 1855, 792, 849], [1877, 2207, 785, 851], [2269, 2888, 781, 848], [2907, 2977, 787, 842], [1431, 2089, 865, 946], [2139, 2372, 868, 934], [2395, 2692, 864, 933], [2731, 3061, 864, 928], [1436, 1727, 956, 1023], [1789, 2302, 954, 1023], [2371, 2541, 953, 1040], [2567, 2753, 957, 1014], [2794, 3043, 946, 1015], [1442, 1582, 1050, 1107], [1614, 1805, 1044, 1106], [1846, 2307, 1042, 1103], [2372, 2416, 1044, 1093], [2439, 3017, 1034, 1098], [1444, 1838, 1127, 1193], [1885, 2210, 1115, 1196], [2241, 2839, 1119, 1186], [2863, 2969, 1117, 1174], [1449, 1877, 1212, 1278], [1925, 2149, 1207, 1274], [2182, 2304, 1213, 1270], [2339, 2744, 1204, 1268], [2781, 2907, 1208, 1259], [1446, 1859, 1292, 1358], [1895, 2022, 1301, 1346], [2045, 2323, 1292, 1353], [2387, 2943, 1282, 1354], [1457, 1645, 1377, 1441], [1668, 1934, 1379, 1441], [1989, 2263, 1375, 1432], [2309, 3021, 1363, 1442], [1444, 1701, 1462, 1526], [1728, 1838, 1462, 1523], [1882, 1988, 1457, 1521], [2024, 2426, 1457, 1521], [2471, 2866, 1449, 1522], [1453, 1817, 1540, 1615], [1860, 1917, 1545, 1605], [1945, 2123, 1545, 1602], [2145, 2200, 1564, 1601], [2209, 2414, 1537, 1604], [2462, 2659, 1538, 1604], [2695, 3024, 1534, 1596], [1444, 1536, 1622, 1686], [1558, 2393, 1603, 1703], [2448, 2938, 1613, 1692], [1453, 2167, 1702, 1780], [2222, 2339, 1703, 1775], [2374, 2943, 1688, 1767], [1444, 1831, 1788, 1866], [1868, 2017, 1794, 1855], [2043, 2641, 1784, 1858], [2681, 2759, 1817, 1857], [2767, 2918, 1781, 1853], [1441, 1686, 1880, 1944], [1745, 2012, 1868, 1945], [2066, 2173, 1870, 1935], [2212, 2774, 1872, 1936], [2795, 3074, 1869, 1937], [1448, 1571, 1966, 2026], [1606, 2042, 1960, 2026], [2110, 2224, 1968, 2023], [2272, 2583, 1954, 2019], [2629, 2737, 1961, 2018], [2778, 2910, 1950, 2016], [1444, 1606, 2042, 2106], [1634, 2657, 2033, 2110], [2709, 2974, 2026, 2105], [1458, 1682, 2126, 2200], [1713, 2206, 2121, 2196], [2270, 2397, 2118, 2186], [2429, 2800, 2117, 2186], [2828, 2994, 2118, 2185], [1466, 1584, 2206, 2278], [1624, 2011, 2210, 2274], [2050, 2157, 2208, 2273], [2194, 2426, 2205, 2271], [2478, 2578, 2202, 2266], [2616, 3013, 2199, 2273], [1464, 1575, 2295, 2356], [1633, 1749, 2296, 2353], [1789, 2084, 2293, 2354], [2194, 2449, 2285, 2362], [2475, 2746, 2287, 2354], [2812, 2923, 2288, 2345]]], [[]])

All of the numbers you see here are the proper output for the orthogonal text boxes, but you can see at the very end of the list, is an empty list which should contain free-form text boxes in the format [[x1,y1],[x2,y2],[x3,y3],[x4,y4]].

I.e., the documentation says it should return: Return horizontal_list, free_list - horizontal_list is a list of regtangular text boxes. The format is [x_min, x_max, y_min, y_max]. free_list is a list of free-form text boxes. The format is [[x1,y1],[x2,y2],[x3,y3],[x4,y4]]. "

Is anybody else having this problem? Does anyone know what the cause is/how to fix it? I hope it doesn't turn out to be the case that I'm just making a total rookie mistake, lul. I looked around the discussion pages and documentation and haven't seemed to find any mention of it. Thanks

Also having this problem, was curious if a solution was found. The free boxes get posted occasionally, but no consistently.

Seem to have figured this out. The model doesn't return both, it returns a collection of some horizontal boxes and some free boxes. The boxes that are horizontal are determined by the slope threshold, which automatically rotates the boxes that fit the threshold and thus return those boxes as horizontal, with the boxes that exceed the threshold being returned as free boxes. To obtain all the boxes as free boxes, set the slope threshold to 0, and all boxes will return as free boxes.

Seem to have figured this out. The model doesn't return both, it returns a collection of some horizontal boxes and some free boxes. The boxes that are horizontal are determined by the slope threshold, which automatically rotates the boxes that fit the threshold and thus return those boxes as horizontal, with the boxes that exceed the threshold being returned as free boxes. To obtain all the boxes as free boxes, set the slope threshold to 0, and all boxes will return as free boxes.

Ohhhhhh. Sweet, it look like you figured out what was going on. Thanks a lot, eh.

I have a program using EasyOCR that works great, but when I try to change it to use EasyOCR's detection of text with rotation/skewness etc., as opposed to just orthogonal boxes, (or as it's called in the documentation, the 'free_list', which is returned by easyocr.detect()), it does not seem to work. Specifically, here is the code and the output: The code:
